 1. Change directories to the root of the repository.
 1. Run the docker build command. `docker build -t mono-choco -f docker/Dockerfile.linux .` (the trailing . is important)
+    To build a official version, add the argument `--build-arg buildscript=build.official.sh`
+    To build a debug version, add the argument `--build-arg buildscript=build.official.sh`
+    To change the version of mono used, add the argument `--build-arg monoversion=mono-tag`
 1. Run your new image using the command `docker run -ti --rm mono-choco /bin/bash`
