 # Compile from source
 
+- Clone this repo
 - Follow [ebitengine's install guide][6]
 - Run: `go build -tags ebitensinglethread -o dist/`
 - Your compiled binary should now be in `./dist/`
 
+Alternatively, if you already have Go, you can run `go run
+go.imnhan.com/shark@latest` to compile and run the latest version without
+manually cloning the repo. You still need to install ebiten's dependencies
+first though.

 Apparently it should compile on FreeBSD too but I haven't tried that.
 Do let me know if it works on your FreeBSD desktop!
