+# Contributing to Avalonia
+
+## Before You Start
+
+Drop into our [gitter chat room](https://gitter.im/AvaloniaUI/Avalonia) and let us know what you're thinking of doing. We might be able to give you guidance or let you know if someone else is already working on the feature.
+
+## Style
+
+The codebase uses [.net core](https://github.com/dotnet/runtime/blob/master/docs/coding-guidelines/coding-style.md) coding style.
+
+Try to keep lines of code around 100 characters in length or less, though this is not a hard limit.
+If you're a few characters over then don't worry too much.
+
+**DO NOT USE #REGIONS** full stop.
+
+## Pull requests
+
+A single pull request should be submitted for each change. If you're making more than one change,
+please submit separate pull requests for each change for easy review. Rebase your changes to make
+sense, so a history that looks like:
+
+* Add class A
+* Feature A didn't set Foo when Bar was set
+* Fix spacing
+* Add class B
+* Sort using statements
+
+Should be rebased to read:
+
+* Add class A
+* Add class B
+
+Again, this makes review much easier.
+
+Please try not to submit pull requests that don't add new features (e.g. moving stuff around)
+unless you see something that is obviously wrong or that could be written in a more terse or
+idiomatic style. It takes time to review each pull request - time that I'd prefer to spend writing
+new features!
+
+Prefer terseness to verbosity but don't try to be too clever.
+
+## Tests
+
+There are two types of tests currently in the codebase; unit tests and render tests.
+
+Unit tests should be contained in a class name that mirrors the class being tested with the suffix
+-Tests, e.g.
+
+    Avalonia.Controls.UnitTests.Presenters.TextPresenterTests
+
+Where Avalonia.Controls.UnitTests is the name of the project.
+
+Unit test methods should be named in a sentence style, separated by underscores, that describes in
+English what the test is testing, e.g.
+
+```csharp
+    void Calling_Foo_Should_Increment_Bar()
+```
+
+Render tests should describe what the produced image is:
+
+```csharp
+    void Rectangle_2px_Stroke_Filled()
+```
+
+## Code of Conduct
+
+This project has adopted the code of conduct defined by the Contributor Covenant to clarify expected behavior in our community.
+For more information see the [Contributor Covenant Code of Conduct](https://dotnetfoundation.org/code-of-conduct)

+# Windows
+
+Avalonia requires at least Visual Studio 2019 and .NET Core SDK 3.1 to build on Windows.
+
+###  Clone the Avalonia repository
+
+```
+git clone https://github.com/AvaloniaUI/Avalonia.git
+git submodule update --init
+```
+
+###  Open in Visual Studio
+
+Open the `Avalonia.sln` solution in Visual Studio 2019 or newer. The free Visual Studio Community
+edition works fine. Run the `Samples\ControlCatalog.Desktop` project to see the sample application.
+
+# Linux/macOS
+
+It's *not* possible to build the *whole* project on Linux/macOS. You can only build the subset targeting .NET Standard and .NET Core (which is, however, sufficient to get UI working on Linux/macOS). If you want to something that involves changing platform-specific APIs you'll need a Windows machine.
+
+MonoDevelop, Xamarin Studio and Visual Studio for Mac aren't capable of properly opening our solution. You can use Rider (at least 2017.2 EAP) or VSCode instead. They will fail to load most of platform specific projects, but you don't need them to run on .NET Core.
+
+###  Install the latest version of .NET Core
+
+Go to https://www.microsoft.com/net/core and follow instructions for your OS. You need SDK (not just "runtime") package.
+
+###  Additional requirements for macOS
+
+The build process needs [Xcode](https://developer.apple.com/xcode/) to build the native library.  Following the install instructions at the [Xcode](https://developer.apple.com/xcode/) website to properly install.
+
+Linux operating systems ship with their own respective package managers however we will use [Homebrew](https://brew.sh/) to manage packages on macOS.  To install follow the instructions [here](https://docs.brew.sh/Installation).
+
+###  Install CastXML
+
+Avalonia requires [CastXML](https://github.com/CastXML/CastXML) for XML processing during the build process.  The easiest way to install this is via the operating system's package managers, such as below.
+
+On macOS:
+```
+brew install castxml
+```
+
+On Debian based Linux (Debian, Ubuntu, Mint, etc):
+```
+sudo apt install castxml
+```
+
+On Red Hat based Linux (Fedora, CentOS, RHEL, etc) using `yum` (`dnf` takes same arguments though):
+```
+sudo yum install castxml
+```
+
+
+###  Clone the Avalonia repository
+
+```
+git clone https://github.com/AvaloniaUI/Avalonia.git
+cd Avalonia
+git submodule update --init --recursive
+```
+
+### Build native libraries (macOS only)
+
+On macOS it is necessary to build and manually install the respective native libraries using [Xcode](https://developer.apple.com/xcode/).  The steps to get this working correctly are:
+- Navigate to the Avalonia/native/Avalonia.Native/src/OSX folder and open the `Avalonia.Native.OSX.xcodeproj` project
+- Build the library via the Product->Build menu.  This will generate binaries in your local path under ~/Library/Developer/Xcode/DerivedData/Avalonia.Native.OSX-*guid* where "guid" is uniquely generated every time you build.
+- Manually install the native library by copying it from the build artifacts folder into the shared dynamic library path:
+
+```
+cd ~/Library/Developer/Xcode/DerivedData/Avalonia.Native.OSX-[guid]/Build/Products/Debug
+cp libAvalonia.Native.OSX.dylib /usr/local/lib/libAvaloniaNative.dylib
+```
+
+###  Build and Run Avalonia
+
+```
+cd samples/ControlCatalog.NetCore
+dotnet restore
+dotnet run
+```

-Avalonia [Visual Studio Extension](https://marketplace.visualstudio.com/items?itemName=AvaloniaTeam.AvaloniaforVisualStudio) contains project and control templates that will help you get started. After installing it, open "New Project" dialog in Visual Studio, choose "Avalonia" in "Visual C#" section, select "Avalonia .NET Core Application" and press OK (<a href="http://avaloniaui.net/docs/quickstart/images/new-project-dialog.png">screenshot</a>). Now you can write code and markup that will work on multiple platforms!

-For those without Visual Studio, a starter guide for .NET Core CLI can be found [here](http://avaloniaui.net/docs/quickstart/create-new-project#net-core).

-## Documentation
+## Bleeding Edge Builds
 
-You can take a look at the [getting started page](http://avaloniaui.net/docs/quickstart/) for an overview of how to get started but probably the best thing to do for now is to already know a little bit about WPF/Silverlight/UWP/XAML and ask questions in our [Gitter room](https://gitter.im/AvaloniaUI/Avalonia). 
+We also have a [nightly build](https://github.com/AvaloniaUI/Avalonia/wiki/Using-nightly-build-feed) which tracks the current state of master. Although these packages are less stable than the release on NuGet.org, you'll get all the latest features and bugfixes right away and many of our users actually prefer this feed!
 
-There's also a high-level [architecture document](http://avaloniaui.net/architecture/project-structure) that is currently a little bit out of date, and I've also started writing blog posts on Avalonia at http://grokys.github.io/.
+## Documentation
 
-Contributions for our docs are always welcome!
+Documentation can be found on our website at http://avaloniaui.net/docs/. We also have a [tutorial](http://avaloniaui.net/docs/tutorial/) over there for newcomers.
