+
+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+We as members, contributors, and leaders pledge to make participation in our
+community a harassment-free experience for everyone, regardless of age, body
+size, visible or invisible disability, ethnicity, sex characteristics, gender
+identity and expression, level of experience, education, socio-economic status,
+nationality, personal appearance, race, religion, or sexual identity
+and orientation.
+
+We pledge to act and interact in ways that contribute to an open, welcoming,
+diverse, inclusive, and healthy community.
+
+## Our Standards
+
+Examples of behavior that contributes to a positive environment for our
+community include:
+
+* Demonstrating empathy and kindness toward other people
+* Being respectful of differing opinions, viewpoints, and experiences
+* Giving and gracefully accepting constructive feedback
+* Accepting responsibility and apologizing to those affected by our mistakes,
+  and learning from the experience
+* Focusing on what is best not just for us as individuals, but for the
+  overall community
+
+Examples of unacceptable behavior include:
+
+* The use of sexualized language or imagery, and sexual attention or
+  advances of any kind
+* Trolling, insulting or derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or email
+  address, without their explicit permission
+* Other conduct which could reasonably be considered inappropriate in a
+  professional setting
+
+## Enforcement Responsibilities
+
+Community leaders are responsible for clarifying and enforcing our standards of
+acceptable behavior and will take appropriate and fair corrective action in
+response to any behavior that they deem inappropriate, threatening, offensive,
+or harmful.
+
+Community leaders have the right and responsibility to remove, edit, or reject
+comments, commits, code, wiki edits, issues, and other contributions that are
+not aligned to this Code of Conduct, and will communicate reasons for moderation
+decisions when appropriate.
+
+## Scope
+
+This Code of Conduct applies within all community spaces, and also applies when
+an individual is officially representing the community in public spaces.
+Examples of representing our community include using an official e-mail address,
+posting via an official social media account, or acting as an appointed
+representative at an online or offline event.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported to the community leaders responsible for enforcement at
[email protected].
+All complaints will be reviewed and investigated promptly and fairly.
+
+All community leaders are obligated to respect the privacy and security of the
+reporter of any incident.
+
+## Enforcement Guidelines
+
+Community leaders will follow these Community Impact Guidelines in determining
+the consequences for any action they deem in violation of this Code of Conduct:
+
+### 1. Correction
+
+**Community Impact**: Use of inappropriate language or other behavior deemed
+unprofessional or unwelcome in the community.
+
+**Consequence**: A private, written warning from community leaders, providing
+clarity around the nature of the violation and an explanation of why the
+behavior was inappropriate. A public apology may be requested.
+
+### 2. Warning
+
+**Community Impact**: A violation through a single incident or series
+of actions.
+
+**Consequence**: A warning with consequences for continued behavior. No
+interaction with the people involved, including unsolicited interaction with
+those enforcing the Code of Conduct, for a specified period of time. This
+includes avoiding interactions in community spaces as well as external channels
+like social media. Violating these terms may lead to a temporary or
+permanent ban.
+
+### 3. Temporary Ban
+
+**Community Impact**: A serious violation of community standards, including
+sustained inappropriate behavior.
+
+**Consequence**: A temporary ban from any sort of interaction or public
+communication with the community for a specified period of time. No public or
+private interaction with the people involved, including unsolicited interaction
+with those enforcing the Code of Conduct, is allowed during this period.
+Violating these terms may lead to a permanent ban.
+
+### 4. Permanent Ban
+
+**Community Impact**: Demonstrating a pattern of violation of community
+standards, including sustained inappropriate behavior,  harassment of an
+individual, or aggression toward or disparagement of classes of individuals.
+
+**Consequence**: A permanent ban from any sort of public interaction within
+the community.
+
+## Attribution
+
+This Code of Conduct is adapted from the [Contributor Covenant][homepage],
+version 2.0, available at
+https://www.contributor-covenant.org/version/2/0/code_of_conduct.html.
+
+Community Impact Guidelines were inspired by [Mozilla's code of conduct
+enforcement ladder](https://github.com/mozilla/diversity).

+# 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 https://raw.githubusercontent.com/Homebrew/homebrew-core/8a004a91a7fcd3f6620d5b01b6541ff0a640ffba/Formula/castxml.rb
+```
+
+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
+```

-## Getting Started
+## 🚀 Getting Started
 
-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!
+The Avalonia [Visual Studio Extension](https://marketplace.visualstudio.com/items?itemName=AvaloniaTeam.AvaloniaforVisualStudio) contains project and control templates that will help you get started, or you can use the .NET Core CLI. For a starer guide see our [documentation](http://avaloniaui.net/docs/quickstart/create-new-project).
 
-For those without Visual Studio, starter guide for .NET Core CLI can be found [here](http://avaloniaui.net/docs/quickstart/create-new-project#net-core).

+## JetBrains Rider
+
+If you need to develop Avalonia app with JetBrains Rider, go and *vote* on [this issue](https://youtrack.jetbrains.com/issue/RIDER-39247) in their tracker. JetBrains won't do things without their users telling them that they want the feature, so only **YOU** can make it happen.
+
+## 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.
