-There is a good chance that running `build.ps1` ends up in error, with messages such as
-
->The file ...\build\build.ps1 is not digitally signed. You cannot run this script on the current system. For more information about running scripts and setting execution policy, see about_Execution_Policies.

-PowerShell has *Execution Policies* that may prevent the script from running. You can check the current policies with:
-
-    PS> Get-ExecutionPolicy -List

-
-Policies can be `Restricted`, `AllSigned`, `RemoteSigned`, `Unrestricted` and `Bypass`. Scopes can be `MachinePolicy`, `UserPolicy`, `Process`, `CurrentUser`, `LocalMachine`. You need the current policy to be `RemoteSigned`—as long as it is `Undefined`, the script cannot run. You can change the current user policy with:
-

-[D] Do not run  [R] Run once  [S] Suspend  [?] Help (default is "D"):
-
-This is usually caused by the scripts being *blocked*. And that usually happens when the source code has been downloaded as a Zip file. When Windows downloads Zip files, they are marked as *blocked* (technically, they have a Zone.Identifier alternate data stream, with a value of "3" to indicate that they were downloaded from the Internet). And when such a Zip file is un-zipped, each and every single file is also marked as blocked.
-
-The best solution is to unblock the Zip file before un-zipping: right-click the files, open *Properties*, and there should be a *Unblock* checkbox at the bottom of the dialog. If, however, the Zip file has already been un-zipped, it is possible to recursively unblock all files from PowerShell with:
-
-    PS> Get-ChildItem -Recurse *.* | Unblock-File

 ## Notes
 
 Git might have issues dealing with long file paths during build. You may want/need to enable `core.longpaths` support (see [this page](https://github.com/msysgit/msysgit/wiki/Git-cannot-create-a-file-or-directory-with-a-long-path) for details).

-## 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](ISSUE_TEMPLATE.md), 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.org/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 question 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 Atom, 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.org/projects/).
-
-### Your First Code Contribution
-
-Unsure where to begin contributing to Umbraco? You can start by looking through [these `Up for grabs` and issues](http://issues.umbraco.org/issues/U4?q=%28project%3A+%7BU4%7D+Difficulty%3A+%7BVery+Easy%7D+%23Easy+%23Unresolved+Priority%3A+Normal+%23Major+%23Show-stopper+State%3A+-%7BIn+Progress%7D+sort+by%3A+votes+Affected+versions%3A+-6.*+Affected+versions%3A+-4.*%29+OR+%28tag%3A+%7BUp+For+Grabs%7D+%23Unresolved+%29).
-
-The issue list is sorted by total number of upvotes. While not perfect, number of upvotes is a reasonable proxy for impact a given change will have.
-
-### 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.org/documentation/Reference/) is generated
-
-Again, these are guidelines, not strict requirements. 
-
-## 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 bower
-  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.org/apidocs/ui/#/api) (to be found  in `src\Umbraco.Web.UI.Client\src`)
-  * [The rest](https://our.umbraco.org/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?](tools/contributing/defaultbranch.png)
-
-### Building Umbraco from source code
-
-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 ([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](tools/contributing/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.
-
-(More info on how this works: [http://robots.thoughtbot.com/post/5133345960/keeping-a-git-fork-updated](http://robots.thoughtbot.com/post/5133345960/keeping-a-git-fork-updated))
-
-## How do I even 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](tools/contributing/forkrepository.png)
-
-  * **Clone** - when GitHub has created your fork, you can clone it in your favorite Git tool
-  
-  ![Clone the fork](tools/contributing/clonefork.png)
-
-  * **Build** - build your fork of Umbraco locally as described in [building Umbraco from source code](#building-umbraco-from-source-code)
-  * **Change** - make your changes, experiment, have fun, explore and learn, and don't be afraid. We welcome all contributions and will happily give feedback
-  * **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-U4-12345`. This means it's a temporary branch for the particular issue you're working on, in this case `U4-12345`
-  * **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](tools/contributing/createpullrequest.png)
-
-The Umbraco development 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.
-
-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!
-
-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 at this and we'll be nice about it, thanking you for spending your valueable time.
-
-Remember, if an issue is in the `Up for grabs` list or you've asked for some feedback before you send us a PR, your PR will not be closed as unwanted.
-
-## Problems?
-
-Did something not work as expected? Try leaving a note in the ["Contributing to Umbraco"](https://our.umbraco.org/forum/contributing-to-umbraco-cms/) forum, the team monitors that one closely!

-## Why Open Source?
+## Why Open Source? ##
 As an Open Source platform, Umbraco is more than just a CMS. We are transparent with our roadmap for future versions, our incremental sprint planning notes are publicly accessible and community contributions and packages are available for all to use.
 
-## Trying out Umbraco CMS
+## Downloading ##
 
-[Umbraco Cloud](https://umbraco.com) is the easiest and fastest way to use Umbraco yet with full support for all your custom .NET code and intergrations. You're up and running in less than a minute and your life will be made easier with automated upgrades and a built-in deployment engine. We offer a free 14 day trial, no credit card needed.
+The downloadable Umbraco releases live at [https://our.umbraco.org/download](https://our.umbraco.org/download).
 
-If you want to DIY you can [download Umbraco](https://our.umbraco.org/download) either as a ZIP file or via NuGet. It's the same version of Umbraco CMS that powers Umbraco Cloud, but you'll need to find a place to host yourself and handling deployments and upgrades is all down to you.
+## Forums ##
 
-## Community
+Peer-to-peer support is available 24/7 at the community forum on [https://our.umbraco.org](https://our.umbraco.org). 
 
-Our friendly community is available 24/7 at the community hub we call ["Our Umbraco"](https://our.umbraco.org). Our Umbraco feature forums for questions and answers, documentation, downloadable plugins for Umbraco and a rich collection of community resources.
