-Experimenting with using Travis for a Racket project.
+Experimenting with using Travis CI for a Racket project.
 
-Travis doesn't have built-in support for Racket. However it seems this
-should be do-able, anyway, by using `before_install` to install
-Racket?
+Until Travis CI gets built-in support for Racket, we can use the
+`before_install` clause of `.travis.yml` to download and run the
+Racket installer.
+
+> **CAVEAT**: This downloads the ~75MB Racket installer and runs it
+> for **each and every** build! In other words, this is a hack. The
+> un-hack would be (IIUC) to add a Travis CI "cookbook" for Racket.
+
+To add this capability to your project, simply add the
+[example `.travis.yml`](https://github.com/greghendershott/travis-racket/blob/master/.travis.yml)
+to your repo. You may need to change its `script` section's `raco
+make` and `raco test` parts.
