-In order to use Umbraco as a CMS and build your website with it, you should not build it yourself. If you're reading this then you're trying to contribute to Umbraco or you're debugging a complex issue.
-
- Are you about to create a pull request for Umbraco?
- Are you trying to get to the bottom of a problem in your existing Umbraco installation?
-
-If the answer is yes, please read on. Otherwise, make sure to head on over [to the download page](https://our.umbraco.com/download) and start using Umbraco CMS as intended.

+To build Umbraco, fire PowerShell and move to Umbraco's repository root (the directory that contains `src`, `build`, `README.md`...). There, trigger the build with the following command:

    build/build.ps1
    
-You might run into [Powershell quirks](#powershell-quirks).
-
-### Build Infrastructure
-
-The Umbraco Build infrastructure relies on a PowerShell object. The object can be retrieved with:
-
-    $ubuild = build/build.ps1 -get
-
-The object exposes various properties and methods that can be used to fine-grain build Umbraco. Some, but not all, of them are detailed below.
-    
-#### Properties
-
-The object exposes the following properties:
-
-* `SolutionRoot`: the absolute path to the solution root
-* `VisualStudio`: a Visual Studio object (see below)
-* `NuGet`: the absolute path to the NuGet executable
-* `Zip`: the absolute path to the 7Zip executable
-* `VsWhere`: the absolute path to the VsWhere executable
-* `NodePath`: the absolute path to the Node install
-* `NpmPath`: the absolute path to the Npm install
-
-The Visual Studio object is `null` when Visual Studio has not been detected (eg on VSTS). When not null, the object exposes the following properties:
-
-* `Path`: Visual Studio installation path (eg some place under `Program Files`)
-* `Major`: Visual Studio major version (eg `15` for VS 2017)
-* `Minor`: Visual Studio minor version
-* `MsBUild`: the absolute path to the MsBuild executable
-
-#### GetUmbracoVersion
-
-Gets an object representing the current Umbraco version. Example:
-
-    $v = $ubuild.GetUmbracoVersion()
-    Write-Host $v.Semver
-
-The object exposes the following properties:
-
-* `Semver`: the semver object representing the version
-* `Release`: the main part of the version (eg `7.6.33`)
-* `Comment`: the pre release part of the version (eg `alpha02`)
-* `Build`: the build number part of the version (eg `1234`)
-
-#### SetUmbracoVersion
-
-Modifies Umbraco files with the new version.
-
->This entirely replaces the legacy `UmbracoVersion.txt` file. Do *not* edit version infos in files.
-
-The version must be a valid semver version. It can include a *pre release* part (eg `alpha02`) and/or a *build number* (eg `1234`). Examples:
-
-    $ubuild.SetUmbracoVersion("7.6.33")
-    $ubuild.SetUmbracoVersion("7.6.33-alpha.2")
-    $ubuild.SetUmbracoVersion("7.6.33+1234")
-    $ubuild.SetUmbracoVersion("7.6.33-beta.5+5678")
-
-#### Build
-
-Builds Umbraco. Temporary files are generated in `build.tmp` while the actual artifacts (zip files, NuGet packages...) are produced in `build.out`. Example:
-
-    $ubuild.Build()
-
-Some log files, such as MsBuild logs, are produced in `build.tmp` too. The `build` directory should remain clean during a build.
-
-**Note: web.config**
-
-Building Umbraco requires a clean `web.config` file in the `Umbraco.Web.UI` project. If a `web.config` file already exists, the `pre-build` task (see below) will save it as `web.config.temp-build` and replace it with a clean copy of `web.Template.config`. The original file is replaced once it is safe to do so, by the `pre-packages` task.
-
-#### Build-UmbracoDocs
-
-Builds umbraco documentation. Temporary files are generated in `build.tmp` while the actual artifacts (docs...) are produced in `build.out`. Example:
-
-    Build-UmbracoDocs
-
-Some log files, such as MsBuild logs, are produced in `build.tmp` too. The `build` directory should remain clean during a build.
-
-#### Verify-NuGet
-
-Verifies that projects all require the same version of their dependencies, and that NuSpec files require versions that are consistent with projects. Example:
-
-    Verify-NuGet
-
-### Cleaning up
-
-Once the solution has been used to run a site, one may want to "reset" the solution in order to run a fresh new site again.
-
-At the very minimum, you want
-
-    git clean -Xdf src/Umbraco.Web.UI/App_Data
-    rm src/Umbraco.Web.UI/web.config
-
-Then, a simple 'Rebuild All' in Visual Studio will recreate a fresh `web.config` but should be quite fast (since it does not really need to rebuild anything).
-
-The `clean` Git command force (`-f`) removes (`-X`, note the capital X) all files and directories (`-d`) that are ignored by Git.
-
-This will leave media files and views around, but in most cases, it will be enough.
-
-To perform a more complete clear, you will want to also delete the content of the media, views, scripts... directories.
-
-The following command will force remove all untracked files and directories, whether they are ignored by Git or not. Combined with `git reset` it can recreate a pristine working directory. 
-
-    git clean -xdf .
-    
-For git documentation see:
-* git [clean](<https://git-scm.com/docs/git-clean>)
-* git [reset](<https://git-scm.com/docs/git-reset>)
-
-## Azure DevOps
-
-Umbraco uses Azure DevOps for continuous integration, nightly builds and release builds. The Umbraco CMS project on DevOps [is available for anonymous users](https://umbraco.visualstudio.com/Umbraco%20Cms).
-
-DevOps uses the `Build-Umbraco` command several times, each time passing a different *target* parameter. The supported targets are:
-
-* `pre-build`: prepares the build
-* `compile-belle`: compiles Belle
-* `compile-umbraco`: compiles Umbraco
-* `pre-tests`: prepares the tests
-* `compile-tests`: compiles the tests
-* `pre-packages`: prepares the packages
-* `pkg-zip`: creates the zip files
-* `pre-nuget`: prepares NuGet packages
-* `pkg-nuget`: creates NuGet packages
-
-All these targets are executed when `Build-Umbraco` is invoked without a parameter (or with the `all` parameter). On VSTS, compilations (of Umbraco and tests) are performed by dedicated DevOps tasks. Similarly, creating the NuGet packages is also performed by dedicated DevOps tasks.
-
-Finally, the produced artifacts are published in two containers that can be downloaded from DevOps: `zips` contains the zip files while `nuget` contains the NuGet packages.
-
->During a DevOps build, some environment `UMBRACO_*` variables are exported by the `pre-build` target and can be reused in other targets *and* in DevOps tasks. The `UMBRACO_TMP` environment variable is used in `Umbraco.Tests` to disable some tests that have issues with DevOps at the moment.

+
+# Notes
+
+*This part needs to be cleaned up*
+
+Nightlies should use some sort of build number.
+
+We should increment versions as soon as a version is released. Ie, as soon as `7.6.33` is released, we should `Set-UmbracoVersion 7.6.34-alpha` and push.
+
+NuGet / NuSpec consistency checks are performed in tests. We should move it so it is done as part of the PowerShell script even before we try to compile and run the tests.

-## Contributing code changes
-
-This document gives you a quick overview on how to get started.
-
-### Guidelines for contributions we welcome
-
-Not all changes are wanted, so on occassion we might close a PR without merging it. We will give you feedback why we can't accept your changes and we'll be nice about it, thanking you for spending your valuable time.
-
-We have [documented what we consider small and large changes](CONTRIBUTION_GUIDELINES.md). Make sure to talk to us before making large changes.
-
-Remember, if an issue is in the `Up for grabs` list or you've asked for some feedback before you sent us a PR, your PR will not be closed as unwanted.
-
-### What can I start with?
-
-Unsure where to begin contributing to Umbraco? You can start by looking through [these `Up for grabs` issues](https://github.com/umbraco/Umbraco-CMS/issues?utf8=%E2%9C%93&q=is%3Aissue+is%3Aopen+label%3Acommunity%2Fup-for-grabs+)
-
-### How do I begin?
-
-Great question! The short version goes like this:
-
-  * **Fork** - create a fork of [`Umbraco-CMS` on GitHub](https://github.com/umbraco/Umbraco-CMS)
-
-  ![Fork the repository](img/forkrepository.png)
-
-  * **Clone** - when GitHub has created your fork, you can clone it in your favorite Git tool
-
-  ![Clone the fork](img/clonefork.png)
-
-  * **Build** - build your fork of Umbraco locally as described in [building Umbraco from source code](BUILD.md)
-  * **Change** - make your changes, experiment, have fun, explore and learn, and don't be afraid. We welcome all contributions and will [happily give feedback](#questions)
-  * **Commit** - done? Yay! 🎉 **Important:** create a new branch now and name it after the issue you're fixing, we usually follow the format: `temp-12345`. This means it's a temporary branch for the particular issue you're working on, in this case `12345`. When you have a branch, commit your changes. Don't commit to `v8/dev`, create a new branch first.
-  * **Push** - great, now you can push the changes up to your fork on GitHub
-  * **Create pull request** - exciting! You're ready to show us your changes (or not quite ready, you just need some feedback to progress). GitHub has picked up on the new branch you've pushed and will offer to create a Pull Request. Click that green button and away you go.
-
-  ![Create a pull request](img/createpullrequest.png)
-
-### Pull requests
-The most successful pull requests usually look a like this:
-
-  * Fill in the required template
-  * Include screenshots and animated GIFs in your pull request whenever possible.
-  * Unit tests, while optional are awesome, thank you!
-  * New code is commented with documentation from which [the reference documentation](https://our.umbraco.com/documentation/Reference/) is generated
-
-Again, these are guidelines, not strict requirements.
-
-## Reviews
-
-You've sent us your first contribution, congratulations! Now what?
-
-The [pull request team](#the-pr-team) can now start reviewing your proposed changes and give you feedback on them. If it's not perfect, we'll either fix up what we need or we can request you to make some additional changes.
-
-We have [a process in place which you can read all about](REVIEW_PROCESS.md). The very abbreviated version is:
-
- Your PR will get a reply within 48 hours
- An in-depth reply will be added within at most 2 weeks
- The PR will be either merged or rejected within at most 4 weeks
- Sometimes it is difficult to meet these timelines and we'll talk to you
-
-### Styleguides
-
-To be honest, we don't like rules very much. We trust you have the best of intentions and we encourage you to create working code. If it doesn't look perfect then we'll happily help clean it up.
-
-That said, the Umbraco development team likes to follow the hints that ReSharper gives us (no problem if you don't have this installed) and we've added a `.editorconfig` file so that Visual Studio knows what to do with whitespace, line endings, etc.
-
-### The PR team
-
-The pull request team consists of a member of Umbraco HQ, [Sebastiaan](https://github.com/nul800sebastiaan), who gets assistance from the following community members
-
- [Anders Bjerner](https://github.com/abjerner)
- [Dave Woestenborghs](https://github.com/dawoe)
- [Emma Burstow](https://github.com/emmaburstow)
- [Poornima Nayar](https://github.com/poornimanayar)
-
-These wonderful volunteers will provide you with a first reply to your PR, review and test out your changes and might ask more questions. After that they'll let Umbraco HQ know if everything seems okay.
-
-### Questions?
-
-You can get in touch with [the PR team](#the-pr-team) in multiple ways, we love open conversations and we are a friendly bunch. No question you have is stupid. Any questions you have usually helps out multiple people with the same question. Ask away:
-
- If there's an existing issue on the issue tracker then that's a good place to leave questions and discuss how to start or move forward
- Unsure where to start? Did something not work as expected? Try leaving a note in the ["Contributing to Umbraco"](https://our.umbraco.com/forum/contributing-to-umbraco-cms/) forum, the team monitors that one closely
-
-## Working with the code
-
-### Building Umbraco from source code
-
-In order to build the Umbraco source code locally, first make sure you have the following installed.
-
-  * Visual Studio 2017 v15.9.7+
-  * Node v10+
-  * npm v6.4.1+
-
-The easiest way to get started is to run `build.ps1` which will build both the backoffice (also known as "Belle") and the Umbraco core. You can then easily start debugging from Visual Studio, or if you need to debug Belle you can run `gulp dev` in `src\Umbraco.Web.UI.Client`. See [this page](BUILD.md) for more details.
-
-Alternatively, you can open `src\umbraco.sln` in Visual Studio 2017 (version 15.9.7 or higher, [the community edition is free](https://www.visualstudio.com/thank-you-downloading-visual-studio/?sku=Community&rel=15) for you to use to contribute to Open Source projects). In Visual Studio, find the Task Runner Explorer (in the View menu under Other Windows) and run the build task under the gulpfile.
-
-![Gulp build in Visual Studio](img/gulpbuild.png)
-
-After this build completes, you should be able to hit `F5` in Visual Studio to build and run the project. A IISExpress webserver will start and the Umbraco installer will pop up in your browser, follow the directions there to get a working Umbraco install up and running.
-
-### Working with the source code
-
-Some parts of our source code are over 10 years old now. And when we say "old", we mean "mature" of course!
-
-There's two big areas that you should know about:
-
-  1. The Umbraco backoffice is a extensible AngularJS app and requires you to run a `gulp dev` command while you're working with it, so changes are copied over to the appropriate directories and you can refresh your browser to view the results of your changes.
-  You may need to run the following commands to set up gulp properly:
-  ```
-  npm cache clean --force
-  npm install
-  npm run build
-  ```
-  2. "The rest" is a C# based codebase, which is mostly ASP.NET MVC based. You can make changes, build them in Visual Studio, and hit `F5` to see the result.
-
-To find the general areas of something you're looking to fix or improve, have a look at the following two parts of the API documentation.
-
-  * [The AngularJS based backoffice files](https://our.umbraco.com/apidocs/ui/#/api) (to be found  in `src\Umbraco.Web.UI.Client\src`)
-  * [The C# application](https://our.umbraco.com/apidocs/csharp/)
-
-### Which branch should I target for my contributions?
-
-We like to use [Gitflow as much as possible](https://jeffkreeftmeijer.com/git-flow/), don't worry if you are not familiar with it. The most important thing you need to know is that when you fork the Umbraco repository, the default branch is set to something, usually `v8/dev`. Whatever the default is, that's where we'd like you to target your contributions.
-
-![Which branch should I target?](img/defaultbranch.png)
-
-### Making changes after the PR was opened
-
-If you make the corrections we ask for in the same branch and push them to your fork again, the pull request automatically updates with the additional commit(s) so we can review it again. If all is well, we'll merge the code and your commits are forever part of Umbraco!
-
-### Keeping your Umbraco fork in sync with the main repository
-
-We recommend you sync with our repository before you submit your pull request. That way, you can fix any potential merge conflicts and make our lives a little bit easier.
-
-Also, if you've submitted a pull request three weeks ago and want to work on something new, you'll want to get the latest code to build against of course.
-
-To sync your fork with this original one, you'll have to add the upstream url, you only have to do this once:
-
-```
-git remote add upstream https://github.com/umbraco/Umbraco-CMS.git
-```
-
-Then when you want to get the changes from the main repository:
-
-```
-git fetch upstream
-git rebase upstream/v8/dev
-```
-
-In this command we're syncing with the `v8/dev` branch, but you can of course choose another one if needed.

+# Contributing to Umbraco CMS
+
+👍🎉 First off, thanks for taking the time to contribute! 🎉👍
+
+The following is a set of guidelines for contributing to Umbraco CMS.
+
+These are mostly guidelines, not rules. Use your best judgment, and feel free to propose changes to this document in a pull request.
+
+Remember, we're a friendly bunch and are happy with whatever contribution you might provide. Below are guidelines for success that we've gathered over the years. If you choose to ignore them then we still love you 💖.
+
+## Contributing code changes
+
+This document gives you a quick overview on how to get started, we will link to in-depth documentation throughout if you need some more background info.
+
+
+## Guidelines for contributions we welcome
+
+Not all changes are wanted, so on occassion we might close a PR without merging it. We will give you feedback why we can't accept your changes and we'll be nice about it, thanking you for spending your valuable time.
+
+We have [documented what we consider small and large changes](CONTRIBUTION_GUIDELINES.md). Make sure to talk to us before making large changes.
+
+Remember, if an issue is in the `Up for grabs` list or you've asked for some feedback before you sent us a PR, your PR will not be closed as unwanted.
+
+## How do I begin?
+
+Great question! The short version goes like this:
+
+  * **Fork** - create a fork of [`Umbraco-CMS` on GitHub](https://github.com/umbraco/Umbraco-CMS)
+
+  ![Fork the repository](img/forkrepository.png)
+
+  * **Clone** - when GitHub has created your fork, you can clone it in your favorite Git tool
+  
+  ![Clone the fork](img/clonefork.png)
+
+  * **Build** - build your fork of Umbraco locally as described in [building Umbraco from source code](BUILD.md)
+  * **Change** - make your changes, experiment, have fun, explore and learn, and don't be afraid. We welcome all contributions and will [happily give feedback](#questions)
+  * **Commit** - done? Yay! 🎉 It is recommended to create a new branch now and name it after the issue you're fixing, we usually follow the format: `temp-12345`. This means it's a temporary branch for the particular issue you're working on, in this case `12345`
+  * **Push** - great, now you can push the changes up to your fork on GitHub
+  * **Create pull request** - exciting! You're ready to show us your changes (or not quite ready, you just need some feedback to progress). GitHub has picked up on the new branch you've pushed and will offer to create a Pull Request. Click that green button and away you go.
+
+  ![Create a pull request](img/createpullrequest.png)
+
+### Further reading
+
+At this point you might want to [read on about contributing in depth](CONTRIBUTING_DETAILED.md). 
+
+### Reviews
+
+You've sent us your first contribution, congratulations! Now what?
+
+The [pull request team](#the-pr-team) can now start reviewing your proposed changes and give you feedback on them. If it's not perfect, we'll either fix up what we need or we can request you to make some additional changes.
+
+We have [a process in place which you can read all about](REVIEW_PROCESS.md). The very abbreviated version is:
+
+- Your PR will get a reply within 48 hours
+- An in-depth reply will be added within at most 2 weeks
+- The PR will be either merged or rejected within at most 4 weeks
+- Sometimes it is difficult to meet these timelines and we'll talk to you
+
+## Styleguides
+
+To be honest, we don't like rules very much. We trust you have the best of intentions and we encourage you to create working code. If it doesn't look perfect then we'll happily help clean it up.
+
+That said, the Umbraco development team likes to follow the hints that ReSharper gives us (no problem if you don't have this installed) and we've added a `.editorconfig` file so that Visual Studio knows what to do with whitespace, line endings, etc.
+
+## The PR team
+
+The pull request team consists of a member of Umbraco HQ, [Sebastiaan](https://github.com/nul800sebastiaan), who gets assistance from the following community members
+
+- [Anders Bjerner](https://github.com/abjerner)
+- [Dave Woestenborghs](https://github.com/dawoe)
+- [Emma Burstow](https://github.com/emmaburstow)
+- [Poornima Nayar](https://github.com/poornimanayar)
+
+These wonderful volunteers will provide you with a first reply to your PR, review and test out your changes and might ask more questions. After that they'll let Umbraco HQ know if everything seems okay. 
+
+## Questions?
+
+You can get in touch with [the PR team](#the-pr-team) in multiple ways, we love open conversations and we are a friendly bunch. No question you have is stupid. Any questions you have usually helps out multiple people with the same question. Ask away:
+
+- If there's an existing issue on the issue tracker then that's a good place to leave questions and discuss how to start or move forward
+- Unsure where to start? Did something not work as expected? Try leaving a note in the ["Contributing to Umbraco"](https://our.umbraco.com/forum/contributing-to-umbraco-cms/) forum, the team monitors that one closely

+## How Can I Contribute?
+
+### Reporting Bugs
+This section guides you through submitting a bug report for Umbraco CMS. Following these guidelines helps maintainers and the community understand your report 📝, reproduce the behavior 💻 💻, and find related reports 🔎.
+
+Before creating bug reports, please check [this list](#before-submitting-a-bug-report) as you might find out that you don't need to create one. When you are creating a bug report, please [include as many details as possible](#how-do-i-submit-a-good-bug-report). Fill out [the required template](https://github.com/umbraco/Umbraco-CMS/issues/new/choose), the information it asks for helps us resolve issues faster.
+
+> **Note:** If you find a **Closed** issue that seems like it is the same thing that you're experiencing, open a new issue and include a link to the original issue in the body of your new one.
+
+##### Before Submitting A Bug Report
+
+  * Most importantly, check **if you can reproduce the problem** in the [latest version of Umbraco](https://our.umbraco.com/download/). We might have already fixed your particular problem.
+  * It also helps tremendously to check if the issue you're experiencing is present in **a clean install** of the Umbraco version you're currently using. Custom code can have side-effects that don't occur in a clean install.
+  * **Use the Google**. Whatever you're experiencing, Google it plus "Umbraco" - usually you can get some pretty good hints from the search results, including open issues and further troubleshooting hints.
+  * If you do find and existing issue has **and the issue is still open**, add a comment to the existing issue if you have additional information. If you have the same problem and no new info to add, just "star" the issue.
+
+Explain the problem and include additional details to help maintainers reproduce the problem. The following is a long description which we've boiled down into a few very simple questions in the issue tracker when you create a new issue. We're listing the following hints to indicate that the most successful reports usually have a lot of this ground covered:
+
+  * **Use a clear and descriptive title** for the issue to identify the problem.
+  * **Describe the exact steps which reproduce the problem** in as many details as possible. For example, start by explaining which steps you took in the backoffice to get to a certain undesireable result, e.g. you created a document type, inherting 3 levels deep, added a certain datatype, tried to save it and you got an error.
+  * **Provide specific examples to demonstrate the steps**. If you wrote some code, try to provide a code sample as specific as possible to be able to reproduce the behavior.
+  * **Describe the behavior you observed after following the steps** and point out what exactly is the problem with that behavior.
+  * **Explain which behavior you expected to see instead and why.**
+
+Provide more context by answering these questions:
+
+  * **Can you reproduce the problem** when `debug="false"` in your `web.config` file?
+  * **Did the problem start happening recently** (e.g. after updating to a new version of Umbraco) or was this always a problem?
+  * **Can you reliably reproduce the issue?** If not, provide details about how often the problem happens and under which conditions it normally happens.
+
+Include details about your configuration and environment:
+
+  * **Which version of Umbraco are you using?**
+  * **What is the environment you're using Umbraco in?** Is this a problem on your local machine or on a server. Tell us about your configuration: Windows version, IIS/IISExpress, database type, etc.
+  * **Which packages do you have installed?**
+
+### Suggesting Enhancements
+
+This section guides you through submitting an enhancement suggestion for Umbraco, including completely new features and minor improvements to existing functionality. Following these guidelines helps maintainers and the community understand your suggestion 📝 and find related suggestions 🔎.
+
+Most of the suggestions in the [reporting bugs](#reporting-bugs) section also count for suggesting enhancements.
+
+Some additional hints that may be helpful:
+
+  * **Include screenshots and animated GIFs** which help you demonstrate the steps or point out the part of Umbraco which the suggestion is related to.
+  * **Explain why this enhancement would be useful to most Umbraco users** and isn't something that can or should be implemented as a [community package](https://our.umbraco.com/projects/).
+
+### Your First Code Contribution
+
+Unsure where to begin contributing to Umbraco? You can start by looking through [these `Up for grabs` and issues](https://issues.umbraco.org/issues?q=&project=U4&tagValue=upforgrabs&release=&issueType=&search=search) or on the [new issue tracker](https://github.com/umbraco/Umbraco-CMS/issues?q=is%3Aopen+is%3Aissue+label%3Acommunity%2Fup-for-grabs).
+
+### Pull Requests
+
+The most successful pull requests usually look a like this:
+
+  * Fill in the required template
+  * Include screenshots and animated GIFs in your pull request whenever possible.
+  * Unit tests, while optional are awesome, thank you!
+  * New code is commented with documentation from which [the reference documentation](https://our.umbraco.com/documentation/Reference/) is generated
+
+Again, these are guidelines, not strict requirements.
+
+## Making changes after the PR was opened
+
+If you make the corrections we ask for in the same branch and push them to your fork again, the pull request automatically updates with the additional commit(s) so we can review it again. If all is well, we'll merge the code and your commits are forever part of Umbraco!
+
+## Styleguides
+
+To be honest, we don't like rules very much. We trust you have the best of intentions and we encourage you to create working code. If it doesn't look perfect then we'll happily help clean it up.
+
+That said, the Umbraco development team likes to follow the hints that ReSharper gives us (no problem if you don't have this installed) and we've added a `.editorconfig` file so that Visual Studio knows what to do with whitespace, line endings, etc.
+
+## What should I know before I get started?
+
+### Working with the source code
+
+Some parts of our source code is over 10 years old now. And when we say "old", we mean "mature" of course!
+
+There's two big areas that you should know about:
+
+  1. The Umbraco backoffice is a extensible AngularJS app and requires you to run a `gulp dev` command while you're working with it, so changes are copied over to the appropriate directories and you can refresh your browser to view the results of your changes.
+  You may need to run the following commands to set up gulp properly:
+  ```
+  npm cache clean
+  npm install -g gulp
+  npm install -g gulp-cli
+  npm install
+  gulp build
+  ```
+  2. "The rest" is a C# based codebase, with some traces of our WebForms past but mostly ASP.NET MVC based these days. You can make changes, build them in Visual Studio, and hit `F5` to see the result.
+
+To find the general areas of something you're looking to fix or improve, have a look at the following two parts of the API documentation.
+
+  * [The AngularJS based backoffice files](https://our.umbraco.com/apidocs/ui/#/api) (to be found  in `src\Umbraco.Web.UI.Client\src`)
+  * [The rest](https://our.umbraco.com/apidocs/csharp/)
+
+### What branch should I target for my contributions?
+
+We like to use [Gitflow as much as possible](https://jeffkreeftmeijer.com/git-flow/), don't worry if you are not familiar with it. The most important thing you need to know is that when you fork the Umbraco repository, the default branch is set to something, usually `dev-v7`. Whatever the default is, that's where we'd like you to target your contributions.
+
+![What branch do you want me to target?](img/defaultbranch.png)
+
+### Building Umbraco from source code
+
+In order to build the Umbraco source code locally, first make sure you have the following installed.
+
+  * Visual Studio 2017 v15.3+
+  * Node v10+ (Installed via `build.bat` script. If you already have it installed, make sure you're running at least v10)
+  * npm v6.4.1+ (Installed via `build.bat` script. If you already have it installed, make sure you're running at least v6.4.1)
+
+The easiest way to get started is to run `build.bat` which will build both the backoffice (also known as "Belle") and the Umbraco core. You can then easily start debugging from Visual Studio, or if you need to debug Belle you can run `gulp dev` in `src\Umbraco.Web.UI.Client`. See [this page](BUILD.md) for more details.
+
+Alternatively, you can open `src\umbraco.sln` in Visual Studio 2017 (version 15.3 or higher, [the community edition is free](https://www.visualstudio.com/thank-you-downloading-visual-studio/?sku=Community&rel=15) for you to use to contribute to Open Source projects). In Visual Studio, find the Task Runner Explorer (in the View menu under Other Windows) and run the build task under the gulpfile.
+
+![Gulp build in Visual Studio](img/gulpbuild.png)
+
+After this build completes, you should be able to hit `F5` in Visual Studio to build and run the project. A IISExpress webserver will start and the Umbraco installer will pop up in your browser, follow the directions there to get a working Umbraco install up and running.
+
+### Keeping your Umbraco fork in sync with the main repository
+
+We recommend you sync with our repository before you submit your pull request. That way, you can fix any potential merge conflicts and make our lives a little bit easier.
+
+Also, if you've submitted a pull request three weeks ago and want to work on something new, you'll want to get the latest code to build against of course.
+
+To sync your fork with this original one, you'll have to add the upstream url, you only have to do this once:
+
+```
+git remote add upstream https://github.com/umbraco/Umbraco-CMS.git
+```
+
+Then when you want to get the changes from the main repository:
+
+```
+git fetch upstream
+git rebase upstream/dev-v7
+```
+
+In this command we're syncing with the `dev-v7` branch, but you can of course choose another one if needed.

+# Contributing to Umbraco CMS
+
+When you’re considering creating a pull request for Umbraco CMS, we will categorize them in two different sizes, small and large.
+
+The process for both sizes is very similar, as [explained in the contribution document](CONTRIBUTING.md#how-do-i-begin).
+
+## Small PRs
+Bug fixes and small improvements - can be recognized by seeing a small number of changes and possibly a small number of new files.
+
+We’re usually able to handle small PRs pretty quickly. A community volunteer will do the initial review and flag it for Umbraco HQ as “community tested”. If everything looks good, it will be merged pretty quickly [as per the described process](REVIEW_PROCESS.md).
+
+### Up for grabs
+
+Umbraco HQ will regularly mark newly created issues on the issue tracker with the `Up for grabs` tag. This means that the proposed changes are wanted in Umbraco but the HQ does not have the time to make them at this time. These issues are usually small enough to fit in the "Small PRs" category and we encourage anyone to pick them up and help out.  
+
+If you do start working on something, make sure to leave a small comment on the issue saying something like: "I'm working on this". That way other people stumbling upon the issue know they don't need to pick it up, someone already has.
+
+## Large PRs
+New features and large refactorings - can be recognized by seeing a large number of changes, plenty of new files, updates to package manager files (NuGet’s packages.config, NPM’s packages.json, etc.).  
+
+We would love to follow the same process for larger PRs but this is not always possible due to time limitations and priorities that need to be aligned. We don’t want to put up any barriers, but this document should set the correct expectations.  
+
+Please make sure to describe your idea in an issue, it helps to put in mockup screenshots or videos.  
+
+If the change makes sense for HQ to include in Umbraco CMS we will leave you some feedback on how we’d like to see it being implemented. 
+
+If a larger pull request is encouraged by Umbraco HQ, the process will be similar to what is described in the [small PRs process](#small-prs) above, we’ll get feedback to you within 14 days. Finalizing and merging the PR might take longer though as it will likely need to be picked up by the development team to make sure everything is in order. We’ll keep you posted on the progress.
+
+### Pull request or package?
+
+If it doesn’t fit in CMS right now, we will likely encourage you to make it into a package instead. A package is a great way to check out popularity of a feature, learn how people use it, validate good usability and to fix bugs.  
+
+Eventually, a package could "graduate" to be included in the CMS.

+
+_Ready to try out Version 8? [See the quick start guide](V8_GETTING_STARTED.md)._
+
+When is Umbraco 8 coming?
+=========================
+When it's ready. We're done with the major parts of the architecture work and are focusing on three separate tracks to prepare Umbraco 8 for release:
+1) Editor Track (_currently in progress_). Without editors, there's no market for Umbraco. So we want to make sure that Umbraco 8 is full of love for editors.
+2) Partner Track. Without anyone implementing Umbraco, there's nothing for editors to update. So we want to make sure that Umbraco 8 is a joy to implement
+3) Contributor Track. Without our fabulous ecosystem of both individual Umbracians and 3rd party ISVs, Umbraco wouldn't be as rich a platform as it is today. We want to make sure that it's easy, straight forward and as backwards-compatible as possible to create packages for Umbraco
+
+Once a track is done, we start releasing previews where we ask people to test the features we believe are ready. While the testing is going on and we gather feedback, we move on to the next track. This doesn't mean that there hasn't already been work done in the area, but that a track focuses on finalizing, polishing and preparing the features for release.

+# Review process
+
+You're an awesome person and have sent us your contribution in the form of a pull request! It's now time to relax for a bit and wait for our response. 
+
+In order to set some expectations, here's what happens next.
+
+## Review process
+
+You will get an initial reply within 48 hours (workdays) to acknowledge that we’ve seen your PR and we’ll pick it up as soon as we can.
+
+You will get feedback within at most 14 days after opening the PR. You’ll most likely get feedback sooner though. Then there are a few possible outcomes:
+
+- Your proposed change is awesome! We merge it in and it will be included in the next minor release of Umbraco
+- If the change is a high priority bug fix, we will cherry-pick it into the next patch release as well so that we can release it as soon as possible
+- Your proposed change is awesome but needs a bit more work, we’ll give you feedback on the changes we’d like to see
+- Your proposed change is awesome but.. not something we’re looking to include at this point. We’ll close your PR and the related issue (we’ll be nice about it!)
+
+## Are you still available?
+
+We understand you have other things to do and can't just drop everything to help us out.   
+So if we’re asking for your help to improve the PR we’ll wait for two weeks to give you a fair chance to make changes. We’ll ask for an update if we don’t hear back from you after that time.  
+
+If we don’t hear back from you for 4 weeks, we’ll close the PR so that it doesn’t just hang around forever. You’re very welcome to re-open it once you have some more time to spend on it.  
+
+There will be times that we really like your proposed changes and we’ll finish the final improvements we’d like to see ourselves. You still get the credits and your commits will live on in the git repository.

+## A quick start guide for getting up and runnning with Umbraco v8
+
+### What you need:
+
+* [Visual Studio 2017 Community (Free)](https://www.visualstudio.com/vs/community/), or Professional, Enterprise, etc... _(**Minimum of Version 15.7** or higher, this is important, you WILL get issues with lesser versions)_
+* .NET Framework 4.7.2 installed, get it here: https://www.microsoft.com/net/download/thank-you/net472?survey=false
+* .NET Framework 4.7.2 developer pack, get it here: https://www.microsoft.com/net/download/thank-you/net472-developer-pack _(be sure this is the ENU file which will be named `NDP472-DevPack-ENU.exe`)_
+* Clone the Umbraco repository using the `dev-v8` branch. If your git client doesn't support specifying the branch as you clone then use the command `git clone --single-branch -b dev-v8 <your fork url>`. _(If you clone the repo using the default v7 branch and then checkout the `dev-v8` branch you **might** get problems)_
+
+### Start the solution
+
+* Open the `/src/umbraco.sln` Visual Studio solution
+* Start the solution (easiest way is to use `ctrl + F5`)
+* When the solution is first built this may take some time since it will restore all nuget and npm packages, build the .net solution and also build the angular solution
+* When the website starts you'll see the Umbraco installer and just follow the prompts
+* You're all set!
+
+### Want to run from a zip instead?
+
+If you just want to try out a few things, you can run the site from a zip file which you can download from here https://github.com/umbraco/Umbraco-CMS/releases/tag/temp8-cg18. 
+
+We recommend running the site with the Visual Studio since you'll be able to remain up to date with the latest source code changes.
+
+### Making code changes
+
+* _[The process for making code changes in v8 is the same as v7](https://github.com/umbraco/Umbraco-CMS/blob/dev-v7/.github/CONTRIBUTING.md)_
+* Any .NET changes you make you just need to compile
+* Any Angular/JS changes you make you will need to make sure you are running the Gulp build. Easiest way to do this is from within Visual Studio in the `Task Runner Explorer`. You can find this window by pressing `ctrl + q` and typing in `Task Runner Explorer`. In this window you'll see all Gulp tasks, double click on the `dev` task, this will compile the angular solution and start a file watcher, then any html/js changes you make are automatically built.  
+* When making js changes, you should have the chrome developer tools open to ensure that cache is disabled
+* If you are only making C# changes and are not touching the UI code at all, you can significantly speed up the VS build by adding an empty file specifically called `~/src/preserve.belle`. The UI (Belle) build will then be skipped during a Rebuild.
+
+### What to work on?
+
+We are keeping track of [known issues and limitations here](http://issues.umbraco.org/issue/U4-11279). These line items will eventually be turned into actual tasks to be worked on. Feel free to help us keep this list updated if you find issues and even help fix some of these items. If there is a particular item you'd like to help fix please mention this on the task and we'll create a sub task for the item to continue discussion there.
+
+There's [a list of tasks for v8 that haven't been completed](https://github.com/umbraco/Umbraco-CMS/labels/release%2F8.0.0). If you are interested in helping out with any of these please mention this on the task. This list will be constantly updated as we begin to document and design some of the other tasks that still need to get done.
