 ### Continuous Integration (CI)
 
-Fruit uses Travis CI for continuous integration. You can see the latest CI runs in Travis CI
-[here](https://travis-ci.org/google/fruit/builds). The CI configuration is defined in
-`extras/scripts/travis_yml_generator.py`, that generates a `.travis.yml` file (which must also be checked in, due to the
-way Travis CI is configured).
+Fruit uses Github actions for continuous integration. You can see the latest CI runs in Github
+[here](https://github.com/google/fruit/actions). The CI configuration is defined in
+`.github/workflows`.
 
-When editing the `travis_yml_generator.py` script you should also update the `.travis.yml` file (in the same commit)
-by running:
