-## A Docker image to build Linux, Windows and Android godot binaries.
-
-The main reason to write this, is to provide a simple way in all platforms to integrate external godot modules and build a custom version of godot.
-
-## usage
-1. Install docker on Linux or docker toolbox on Windows or Mac.
-2. Open a terminal on linux or "Docker Quickstart Terminal" on Windows or Mac.
-3. Run command:
-	- Linux: `cd`
-	- Windows: `cd /c/Users/YOUR_USERNAME`
-	- Mac: `cd /Users/YOUR_USERNAME`
-4. Get godot source code: `git clone https://github.com/godotengine/godot.git`
-5. Run command: `cd godot/tools/docker`
-6. Run command: `docker build -t godot .`(In Linux run Docker commands with `sudo` or add your user to docker group before run the Docker commands). The godot docker image will be build after a while.
-7. Run command:
-	- Linux: `docker run -it --name=godot-dev -v /home/YOUR_USERNAME/godot:/godot-dev/godot godot`
-	- Windows: `docker run -it --name=godot-dev -v /c/Users/YOUR_USERNAME/godot:/godot-dev/godot godot`
-	- Mac: `docker run -it --name=godot-dev -v /Users/YOUR_USERNAME/godot:/godot-dev/godot godot`
-	You are in the godot-dev container and /godot-dev directory now.
-8. Run `./install-android-tools` to download and install all android development tools.
-9. Run command: `source ~/.bashrc`
-10. Run command: `cd godot`
-11. Run command: `scons p=android target=release` to test everything is ok. You can set platform to x11, windows, android, haiku and server.
-
-After use and exit, you can use this environment again by open terminal and type commands: `docker start godot-dev && docker attach godot-dev`.
-
-### Windows and Mac stuffs:
-
-- Speed up compilation:
-	- Exit from container.
-	- Run command: `docker-machine stop`
-	- Open "Oracle VM VirtualBox".
-	- In settings of default VM increase CPU cores and RAM to suitable values.
-	- Run command: `docker-machine start`
-	- Run command: `docker start godot-dev && docker attach godot-dev`
-
-- ssh to VM(can be useful sometimes):
-	- `docker-machine ssh`
-
-Check docker and boot2docker projects for more details.
