+to build mpy-crosses. You'll need some version of gcc for this to work.
 
 ## Setting up libraries
 
-These build tools automatically build .mpy files and zip them up for
-CircuitPython when a new tagged release is created. To add support to a repo
-you need to use the [CircuitPython
-cookiecutter](https://github.com/adafruit/cookiecutter-adafruit-circuitpython)
-to generate `.github/workflows/*.yml`.
+These build tools are intended for use with [Travis CI](https://travis-ci.org)
+to automatically build .mpy files and zip them up for CircuitPython when a new
+tagged release is created.  To add support to a repo you need to:
+
+  1. Use the [CircuitPython cookiecutter](https://github.com/adafruit/cookiecutter-adafruit-circuitpython) to generate .travis.yml.
+  2. For adafruit repositories, simply give the CircuitPythonLibrarians team
+     write access to the repo and Adabot will do the rest.
+
+     Otherwise, go to travis-ci.org and find the repository (it needs to be
+     setup to access your github account, and your github account needs access
+     to write to the repo).  Flip the 'ON' switch on for Travis and the repo,
+     see the Travis docs for more details: https://docs.travis-ci.com/user/getting-started/
+  3. Get a GitHub 'personal access token' which has at least 'public_repo' or
+     'repo' scope: https://help.github.com/articles/creating-an-access-token-for-command-line-use/
+     Keep this token safe and secure!  Anyone with the token will be able to
+     access and write to your GitHub repositories.  Travis will use the token
+     to attach the .mpy files to the release.
+  4. In the Travis CI settings for the repository that was enabled find the
+     environment variable editing page: https://docs.travis-ci.com/user/environment-variables/#Defining-Variables-in-Repository-Settings
+     Add an environment variable named GITHUB_TOKEN and set it to the value
+     of the GitHub personal access token above.  Keep 'Display value in build
+     log' flipped off.
+  5. That's it!  Tag a release and Travis should go to work to add zipped .mpy files
+     to the release.  It takes about a 2-3 minutes for a worker to spin up,
+     build mpy-cross, and add the binaries to the release.
 
 The bundle build will produce one zip file for every major CircuitPython
 release supported containing compatible mpy files and a zip with human readable py files.
