+# Linux
+### 1. Requirements:
+Mono >= 5.4.0 (>= 5.8.0 recommended)
+Please check [here](http://www.mono-project.com/download/) for stable or [here](http://www.mono-project.com/download/alpha/) for an alpha release.  
+NuGet >= 4.4.0  
+msbuild  
+git
+
+### 2. Cloning project
+Clone the entire repository with submodules using
+```
+git clone https://github.com/ppy/osu --recursive
+```
+Then restore NuGet packages from the repository
+```
+nuget restore
+```
+### 3. Compiling
+Simply run `msbuild` where `osu.sln` is located, this will create all binaries in `osu/osu.Desktop/bin/Debug`.
+### 4. Optimizing
+If you want additional performance you can change build type to Release with
+```
+msbuild -p:Configuration=Release
+```
+Additionally, mono provides an AOT utility which attempts to precompile binaries. You can utilize that by running
+```
+mono --aot ./osu\!.exe
+```
+### 5. Troubleshooting
+You may run into trouble with NuGet versioning, as the one in packaging system is almost always out of date. Simply run 
+```
+nuget
+sudo nuget update -self
+```
+**Warning** NuGet creates few config files when it's run for the first time.
+Do not run NuGet as root on the first run or you might run into very peculiar issues.

+# Status

-Rhythm is just a *click* away. The future of [osu!](https://osu.ppy.sh) and the beginning of an open era! Commonly known by the codename *osu!lazer*. Pew pew.
+This is still heavily under development and is not intended for end-user use. This repository is intended for developer collaboration. You're welcome to try and use it but please do not submit bug reports without a patch. Please do not ask for help building or using this software.

-## Status
+# Requirements

-This project is still heavily under development, but is in a state where users are encouraged to try it out and keep it installed alongside the stable *osu!* client. It will continue to evolve over the coming months and hopefully bring some new unique features to the table.
+- A desktop platform that can compile .NET 4.7.1. We recommend using [Visual Studio Community Edition](https://www.visualstudio.com/) (Windows), [Visual Studio for Mac](https://www.visualstudio.com/vs/visual-studio-mac/) (macOS) or [MonoDevelop](http://www.monodevelop.com/download/) (Linux), all of which are free. [Visual Studio Code](https://code.visualstudio.com/) may also be used but requires further setup steps which are not covered here.

-We are accepting bug reports (please report with as much detail as possible). Feature requests are welcome as long as you read and understand the contribution guidelines listed below.
+# Getting Started
+- Clone the repository including submodules (`git clone --recurse-submodules https://github.com/ppy/osu`)
+- Build in your IDE of choice (recommended IDEs automatically restore nuget packages; if you are using an alternative make sure to `nuget restore`)

-Detailed changelogs are published on the [official osu! site](https://osu.ppy.sh/home/changelog).
+# Contributing

-## Requirements
+We welcome all contributions, but keep in mind that we already have a lot of the UI designed. If you wish to work on something with the intention on having it included in the official distribution, please open an issue for discussion and we will give you what you need from a design perspective to proceed. If you want to make *changes* to the design, we recommend you open an issue with your intentions before spending too much time, to ensure no effort is wasted.

- A desktop platform with the [.NET Core 3.1 SDK](https://dotnet.microsoft.com/download) or higher installed.
- When running on Linux, please have a system-wide FFmpeg installation available to support video decoding.
- When running on Windows 7 or 8.1, **[additional prerequisites](https://docs.microsoft.com/en-us/dotnet/core/install/dependencies?tabs=netcore31&pivots=os-windows)** may be required to correctly run .NET Core applications if your operating system is not up-to-date with the latest service packs.
- When developing with mobile, [Xamarin](https://docs.microsoft.com/en-us/xamarin/) is required, which is shipped together with Visual Studio or [Visual Studio for Mac](https://visualstudio.microsoft.com/vs/mac/).
- When working with the codebase, we recommend using an IDE with intelligent code completion and syntax highlighting, such as [Visual Studio 2019+](https://visualstudio.microsoft.com/vs/), [JetBrains Rider](https://www.jetbrains.com/rider/) or [Visual Studio Code](https://code.visualstudio.com/).
+Please make sure you are familiar with the [development and testing](https://github.com/ppy/osu-framework/wiki/Development-and-Testing) procedure we have set up. New component development, and where possible, bug fixing and debugging existing components **should always be done under VisualTests**.

-## Running osu!
+Contributions can be made via pull requests to this repository. We hope to credit and reward larger contributions via a [bounty system](https://www.bountysource.com/teams/ppy). If you're unsure of what you can help with, check out the [list of open issues](https://github.com/ppy/osu/issues).

-### Releases
+Note that while we already have certain standards in place, nothing is set in stone. If you have an issue with the way code is structured; with any libraries we are using; with any processes involved with contributing, *please* bring it up. I welcome all feedback so we can make contributing to this project as pain-free as possible.

-If you are not interested in developing the game, you can still consume our [binary releases](https://github.com/ppy/osu/releases).
+# Licence

-**Latest build:**
-
-| [Windows (x64)](https://github.com/ppy/osu/releases/latest/download/install.exe)  | [macOS 10.12+](https://github.com/ppy/osu/releases/latest/download/osu.app.zip) | [iOS(iOS 10+)](https://osu.ppy.sh/home/testflight) | [Android (5+)](https://github.com/ppy/osu/releases/latest/download/sh.ppy.osulazer.apk)
-| ------------- | ------------- | ------------- | ------------- |
-
- **Linux** users are recommended to self-compile until we have official deployment in place.
-
-If your platform is not listed above, there is still a chance you can manually build it by following the instructions below.
-
-### Downloading the source code
-
-Clone the repository:
-
-```shell
-git clone https://github.com/ppy/osu
-cd osu
-```
-
-To update the source code to the latest commit, run the following command inside the `osu` directory:
-
-```shell
-git pull
-```
-
-### Building
-
-Build configurations for the recommended IDEs (listed above) are included. You should use the provided Build/Run functionality of your IDE to get things going. When testing or building new components, it's highly encouraged you use the `VisualTests` project/configuration. More information on this is provided [below](#contributing).
-
- Visual Studio / Rider users should load the project via one of the platform-specific `.slnf` files, rather than the main `.sln.` This will allow access to template run configurations.
- Visual Studio Code users must run the `Restore` task before any build attempt.
-
-You can also build and run *osu!* from the command-line with a single command:
-
-```shell
-dotnet run --project osu.Desktop
-```
-
-If you are not interested in debugging *osu!*, you can add `-c Release` to gain performance. In this case, you must replace `Debug` with `Release` in any commands mentioned in this document.
-
-If the build fails, try to restore NuGet packages with `dotnet restore`.
-
-_Due to a historical feature gap between .NET Core and Xamarin, running `dotnet` CLI from the root directory will not work for most commands. This can be resolved by specifying a target `.csproj` or the helper project at `build/Desktop.proj`. Configurations have been provided to work around this issue for all supported IDEs mentioned above._
-
-### Testing with resource/framework modifications
-
-Sometimes it may be necessary to cross-test changes in [osu-resources](https://github.com/ppy/osu-resources) or [osu-framework](https://github.com/ppy/osu-framework). This can be achieved by running some commands as documented on the [osu-resources](https://github.com/ppy/osu-resources/wiki/Testing-local-resources-checkout-with-other-projects) and [osu-framework](https://github.com/ppy/osu-framework/wiki/Testing-local-framework-checkout-with-other-projects) wiki pages.
-
-### Code analysis
-
-Before committing your code, please run a code formatter. This can be achieved by running `dotnet format` in the command line, or using the `Format code` command in your IDE.
-
-We have adopted some cross-platform, compiler integrated analyzers. They can provide warnings when you are editing, building inside IDE or from command line, as-if they are provided by the compiler itself.
-
-JetBrains ReSharper InspectCode is also used for wider rule sets. You can run it from PowerShell with `.\InspectCode.ps1`, which is [only supported on Windows](https://youtrack.jetbrains.com/issue/RSRP-410004). Alternatively, you can install ReSharper or use Rider to get inline support in your IDE of choice.
-

If you wish to work on something with the intention of having it included in the official distribution, please open an issue for discussion and we will give you what you need from a design perspective to proceed. If you want to make *changes* to the design, we recommend you open an issue with your intentions before spending too much time to ensure no effort is wasted.
