-# Introduction
-
-These instructions cover building Proton 4.2 or newer on Ubuntu using Docker. It is possible to compile without Docker (with `--no-steam-runtime` option to configure script), but this article does not cover such scenario.
-
-Tested on Ubuntu 18.04.
-
-## Install Docker
-
-Install Docker using the instructions [here](https://docs.docker.com/install/linux/docker-ce/ubuntu/).
-
-Make it start at boot:
-
-    $ sudo systemctl enable docker
-
-Proton build system expects, that Docker can be started by a user, so you need to:
-
-    $ sudo groupadd docker
-    $ sudo usermod -aG docker $USER
-    $ sudo systemctl restart docker
-    $ newgrp docker
-
-Verify that you can run docker commands without sudo (as noted in the [Linux post-installation steps](https://docs.docker.com/install/linux/linux-postinstall/)):
-
-    $ docker run hello-world
-
-Now it's time to reboot your machine.
-
-## Install build dependencies
-
-    $ sudo apt-get install gnupg2 meson gcc g++ fontforge \
-                           mingw-w64 mingw-w64-common mingw-w64-tools
-
-If the repository version of Meson is too old, install using pip:
-
-    $ pip3 install meson
-
-## Obtain the source code
-
-Clone Proton repository using `--recurse-submodules` to automatically initialize all submodules:
-
-    $ git clone --recurse-submodules git@github.com:ValveSoftware/Proton.git proton
-
-Then clone steam-runtime, it should be placed next to Proton repository.
-
-    $ git clone git@github.com:ValveSoftware/steam-runtime.git
-
-## Build Docker images
-
-Before the first Proton compilation, you need to build and install Docker images with the Steam runtime. Each of these steps will take several minutes.
-
-    $ ./steam-runtime/setup_docker.sh amd64 --extra-bootstrap=./proton/steamrt-bootstrap.sh steam-proton-dev
-    $ ./steam-runtime/setup_docker.sh i386 --extra-bootstrap=./proton/steamrt-bootstrap.sh steam-proton-dev32
-
-Once finished, you can check if new images were registered in docker (IMAGE ID will likely be different for you):
-
-    $ docker images
-    REPOSITORY           TAG                 IMAGE ID            CREATED             SIZE
-    steam-proton-dev32   latest              ff2263a37f39        24 minutes ago      1.86GB
-    steam-proton-dev     latest              41907a89f224        30 minutes ago      1.95GB
-    hello-world          latest              fce289e99eb9        12 months ago       1.84kB
-
-## Build
-
-Now it's time to build Proton itself:
-
-    $ mkdir proton-mybuild
-    $ cd proton-mybuild
-    $ ../proton/configure.sh --steam-runtime64=docker:steam-proton-dev --steam-runtime32=docker:steam-proton-dev32 --steam-runtime=$HOME/steam-runtime/runtime/ --build-name="proton-mybuild"
-    $ make
-
-### Possible Make Errors
-
-If you encounter the error `mutex in namespace std does not name a type`, you will need to do the following (as noted on [Stack Overflow](https://stackoverflow.com/questions/14191566/c-mutex-in-namespace-std-does-not-name-a-type)):
-
-    $ cd $(dirname $(which i686-w64-mingw32-g++))
-    $ sudo mv i686-w64-mingw32-g++ i686-w64-mingw32-g++.old
-    $ sudo ln -s ./i686-w64-mingw32-g++-posix i686-w64-mingw32-g++
-    $ cd $(dirname $(which x86_64-w64-mingw32-g++))
-    $ sudo mv x86_64-w64-mingw32-g++ x86_64-w64-mingw32-g++.old
-    $ sudo ln -s ./x86_64-w64-mingw32-g++-posix x86_64-w64-mingw32-g++
-
-If you encounter the error `fatal error: dxgi.h: No such file or directory`, I have not found a good fix, however, you can add this line to the makefile to compile without dxvk:
-
-    NO_DXVK := 1
-
-*If anyone finds a better fix for the above issue, please update this page.*
-
-## Packaging and Installation
-
-To package Proton after successful build:
-
-    $ make dist
-
-To test it you can install your build in Steam client. You need to select `proton-localbuild` in Steam Play settings.
-
-    $ make install
-
-If you want to remove your locally built proton:
-
-    $ rm -rf ~/.local/share/Steam/.../proton-mybuild
