-The `make setup` command tries to do the above.
-
 `make build` produces a local binary in the bin/ folder and `make dist`
 will build an app for distribution in the dist/ folder.
 
-Levels should be copied in from the doodle-masters repo into the
-assets/levels/ folder before building the game.
+The bootstrap.py script does all of the above up to `make dist` so if you need
+fully release the game by hand (e.g. on a macOS host) you can basically get away
+with:
+
+1. Clone the doodle repo and cd into it
+2. Run `bootstrap.py` to fully set up your OS with dependencies and build a
+   release quality version of the game with all latest assets (the script finishes
+   with a `make dist`).
+3. Run `make release` to package the dist/ artifact into platform specific
+   release artifacts (.rpm/.deb/.tar.gz bundles for Linux, .zip for Windows,
+   .dmg if running on macOS) which output into the dist/release/ folder.
+
+Before step 3 you may want to download the latest Guidebook to bundle with
+the game (optional). Grab and extract the tarball and run `make dist && make release`:
+
+```bash
+wget -O - https://download.sketchymaze.com/guidebook.tar.gz | tar -xzvf -
