+## Building
+
+New versions are created by the Github action. You should use those. If you need to build a custom image for some unforeseen reason, the command would look like:
+
+```sh
+docker build -t discourse/ruby:<ruby_version>-<debian_release>-slim --build-arg DEBIAN_RELEASE=<debian_release> --build-arg RUBY_VERSION=<ruby_version> .
+```
