Tested on Ubuntu 17.10 and Ubuntu 16.04 LTS. Should work just as well on other distros however I'm not sure which command will install mingw-w64 correctly

+### If you wish to cross compile from a Linux system to Windows you can quite easily do so.
 
-You may not have a Windows machine handy.
-But thanks to xgo, it is possible to cross-compile games made with Ebiten!
+Start by installing sys/windows from the standard library
+`go get golang.org/x/sys/windows`
 
-You will need xgo:  
+Then you'll need the mingw compiler.
+* Debian/Ubuntu:
+`sudo apt install mingw-w64`  
+_Note:_ If package cannot be found on ubuntu make sure you've added the multiverse repository  
+(`sudo add-apt-repository multiverse`)
 
-```
-go get github.com/karalabe/xgo
-```
+When completed you should be able to cross compile using this:  
+`CGO_ENABLED=1 CXX=x86_64-w64-mingw32-g++ CC=x86_64-w64-mingw32-gcc GOOS=windows GOARCH=amd64 go build file.go`
 
-You will also need Docker:  
-https://www.docker.com/products/overview  
-Make sure docker is in your PATH.
+Since that's quite a messy command to use each time you want to test your program you might wanna set up a bash alias in your .bashrc or .profile file.  
+* `nano ~/.bashrc`
+* add this line  
+`alias LinuxtoWindows="export CXX=x86_64-w64-mingw32-g++ && export CC=x86_64-w64-mingw32-gcc && CGO_ENABLED=1 && GOOS=windows"`  
+to the bottom of the file.
 
-Make sure your Ebiten game is in your GOPATH and run this to cross-compile your game to Windows:  
-
-```
-xgo --targets=windows/* /path/to/ebiten/game/in/gopath
-```
-
-NOTE: make sure you have a couple of GB's space as xgo will download what it needs to cross-compile the game.
+Now you may simply use `LinuxToWindows && go build file.go` to cross compile
