-## Install C compiler
-
-**This step is no longer required as of 1.9.**
-
-For Ebiten 1.8 and before, compilation requires a C compiler like GCC to compile third party libraries used by Ebiten. You would need C compiler like [MinGW](http://www.mingw.org/) on Windows. Visual Studio is not tested.
-
-### Option 1. MinGW official
-
-Get the installer from [MinGW](http://www.mingw.org/) (or [MinGW-w64](http://mingw-w64.org/) for 64bit Windows) and install it, then set `PATH` environment variable. It might be hard to find where to download the installer, and in this case, using scoops would be a good option.
-
-### Option 2. Scoop
-
-You also can get MinGW via [Scoop](http://scoop.sh/). This is the easiest way.
-
-```sh
-scoop install gcc
-```
-
-### Option 3. TDM GCC
-
-Get the installer from [TDM GCC](http://tdm-gcc.tdragon.net/download) and install it. `PATH` will be set by the install so you don't have to care. The problem is that TDM GCC is not updated recently, and the last update was in 2015.

-# Windows Subsystem for Linux
-
-1. Install 'Windows for Subsystem for Linux (https://docs.microsoft.com/en-us/windows/wsl/install-win10)
-2. Install 'Ubuntu' via Windows Store
-
-In the Ubuntu:
-
-1. Set up (add a new user)
-2. `sudo apt update`
-3. `sudo apt upgrade`
-4. `sudo apt install mingw-w64`
-5. Install Linux 'Go' downloaded from https://golang.org (Linux version is required. The download directory is typically `/mnt/c/Users/(yourname)/Downloads`)
-
-If you use go modules, that's done! Ebiten will be downloaded automatically if your lib depends on Ebiten. For example:
-
-```sh
-mkdir test
-cd test
-go mod init example.com/m
