-Experimenting with using Travis CI for a Racket project.
-
-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.
+Until/unless Travis CI gets built-in support for Racket, we can use
+the `install` section of `.travis.yml` to download and run the Racket
+installer.
 
 To add this capability to your project, simply add the
-[example `.travis.yml`](https://github.com/greghendershott/travis-racket/blob/master/.travis.yml)
+[example `.travis.yml`](https://github.com/greghendershott/travis-racket/blob/master/example/.travis.yml)
 to your repo. You may need to change its `script` section's `raco
 make` and `raco test` parts.
 
-> **NOTE:** In the `before_install:` step, be sure to pipe the `install-racket.sh` script to `bash` (_not_ to `sh`).
+> **NOTE:** Use `example/.travis.yml` --- *not* the one in the root of this rrepo, which is intended to test this repo not your project.
