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-You may run into trouble with NuGet versioning, as the one in packaging system is almost always out of date.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