 ### 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 ([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.

+
+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.

+
+## Umbraco - The Friendly CMS
+
+For the first time on the Microsoft platform, there is a free user- and developer-friendly CMS that makes it quick and easy to create websites - and a breeze to build complex web applications. Umbraco has award-winning integration capabilities and supports ASP.NET MVC or Web Forms, including User and Custom Controls, right out of the box.
+
+Umbraco is not only loved by developers, but is a content editor's dream. Enjoy intuitive editing tools, media management, responsive views, and approval workflows to send your content live.
+
+Used by more than 443,000 active websites including Carlsberg, Segway, Amazon and Heinz and **The Official ASP.NET and IIS.NET website from Microsoft** ([https://asp.net](https://asp.net) / [https://iis.net](https://iis.net)), you can be sure that the technology is proven, stable and scalable. Backed by the team at Umbraco HQ, and supported by a dedicated community of over 220,000 craftspeople globally, you can trust that Umbraco is a safe choice and is here to stay.
+
+To view more examples, please visit [https://umbraco.com/case-studies-testimonials/](https://umbraco.com/case-studies-testimonials/)
+
+## 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
+
+[Umbraco Cloud](https://umbraco.com/cloud) is the easiest and fastest way to use Umbraco yet, with full support for all your custom .NET code and integrations. 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.
+
+If you want to DIY, you can [download Umbraco](https://our.umbraco.com/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 it yourself, and handling deployments and upgrades will be all up to you.
+
+## Community
+
+Our friendly community is available 24/7 at the community hub we call ["Our Umbraco"](https://our.umbraco.com). Our Umbraco features forums for questions and answers, documentation, downloadable plugins for Umbraco, and a rich collection of community resources.

 * 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

-Umbraco CMS
-===========
-The friendliest, most flexible and fastest growing ASP.NET CMS used by more than 443,000 websites worldwide: [https://umbraco.com](https://umbraco.com)
-
-[![ScreenShot](img/vimeo.png)](https://vimeo.com/172382998/)
-
-## Umbraco CMS
-Umbraco is a free open source Content Management System built on the ASP.NET platform. Our mission is to help you deliver delightful digital experiences by making Umbraco friendly, simpler and social.

-
-## Umbraco - The Friendly CMS
-
-For the first time on the Microsoft platform, there is a free user and developer friendly CMS that makes it quick and easy to create websites - or a breeze to build complex web applications. Umbraco has award-winning integration capabilities and supports ASP.NET MVC or Web Forms, including User and Custom Controls, out of the box.
-
-Umbraco is not only loved by developers, but is a content editors dream. Enjoy intuitive editing tools, media management, responsive views and approval workflows to send your content live.
-
-Used by more than 443,000 active websites including Carlsberg, Segway, Amazon and Heinz and **The Official ASP.NET and IIS.NET website from Microsoft** ([https://asp.net](https://asp.net) / [https://iis.net](https://iis.net)), you can be sure that the technology is proven, stable and scales. Backed by the team at Umbraco HQ, and supported by a dedicated community of over 220,000 craftspeople globally, you can trust that Umbraco is a safe choice and is here to stay.

-
-## 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
-
-[Umbraco Cloud](https://umbraco.com/cloud) 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.
-
-If you want to DIY you can [download Umbraco](https://our.umbraco.com/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.
-
-## Community
-
-Our friendly community is available 24/7 at the community hub we call ["Our Umbraco"](https://our.umbraco.com). Our Umbraco feature forums for questions and answers, documentation, downloadable plugins for Umbraco and a rich collection of community resources.
-
-## Contribute to Umbraco
