 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

 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).

+The Umbraco Build infrastructure relies on a PowerShell object. The object can be retrieved with:

-# Build

-The Umbraco Build solution relies on a PowerShell module. The module needs to be imported into PowerShell. From within Umbraco's repository root:

-    build\build.ps1 -ModuleOnly

+>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:

-    Set-UmbracoVersion 7.6.33
-    Set-UmbracoVersion 7.6.33-alpha02

+    $ubuild.SetUmbracoVersion("7.6.33-beta.5+5678")

-Note that `Set-UmbracoVersion` enforces a slightly more restrictive naming scheme than what semver would tolerate. The pre release part can only be composed of a-z and 0-9, therefore `alpha033` is considered valid but not `alpha.033` nor `alpha033-preview` nor `RC2` (would need to be lowercased `rc2`). 
-
->It is considered best to add trailing zeroes to pre releases, else NuGet gets the order of versions wrong. So if you plan to have more than 10, but no more that 100 alpha versions, number the versions `alpha00`, `alpha01`, etc.

+## 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... 
+* .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 and ensure you have the `temp8` branch checked out
+
+### 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, npm and bower 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
+* Your all set!
+
+### Making code changes
+
+* _The process for making code changes in v8 is the same as v7_
+* 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
+
+### 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](http://issues.umbraco.org/issues/U4?q=Due+in+version%3A+8.0.0+%23Unresolved+). 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.
