+# 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+You may run into trouble with NuGet versioning, as the one in packaging system is almost always out of date.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.

-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.
+# Status

-## Status
+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.

-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.
+# Requirements

-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.
+- 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.

-## Requirements
+# 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`)

- A desktop platform with the [.NET Core SDK 2.2](https://www.microsoft.com/net/learn/get-started) or higher installed.
- When working with the codebase, we recommend using an IDE with intellisense and syntax highlighting, such as [Visual Studio 2017+](https://visualstudio.microsoft.com/vs/), [Jetbrains Rider](https://www.jetbrains.com/rider/) or [Visual Studio Code](https://code.visualstudio.com/).
- Note that there are **[additional requirements for Windows 7 and Windows 8.1](https://docs.microsoft.com/en-us/dotnet/core/windows-prerequisites?tabs=netcore2x)** which you may need to manually install if your operating system is not up-to-date.
-
-## Running osu!
-
-### Releases
-
-If you are not interested in developing the game, please head over to the [releases](https://github.com/ppy/osu/releases) to download a precompiled build with automatic updating enabled.
-
- Windows (x64) users should download and run `install.exe`.
- macOS users (10.12 "Sierra" and higher) should download and run `osu.app.zip`.
- iOS users can join the [TestFlight beta program](https://t.co/xQJmHkfC18).
-
-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 **including submodules**:
-
-```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 provided below.
-
-> 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`.
-
-#### A note for Linux users
-
-On Linux, the environment variable `LD_LIBRARY_PATH` must point to the build directory, located at `osu.Desktop/bin/Debug/$NETCORE_VERSION`.
-
-`$NETCORE_VERSION` is the version of .NET Core SDK. You can have it with `grep TargetFramework osu.Desktop/osu.Desktop.csproj | sed -r 's/.*>(.*)<\/.*/\1/'`.
-
-For example, you can run osu! with the following command:
-
-```shell
-LD_LIBRARY_PATH="$(pwd)/osu.Desktop/bin/Debug/netcoreapp2.2" dotnet run --project osu.Desktop
-```
-
-### 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
-
-Code analysis can be run with `powershell ./build.ps1` or `build.sh`. This is currently only supported under windows due to [resharper cli shortcomings](https://youtrack.jetbrains.com/issue/RSRP-410004). Alternatively, you can install resharper or use rider to get inline support in your IDE of choice.
