+## Develop
+
+If you want to contribute, use the usual github method of forking and sending
+a pull request.
+
+Before sending a pull request, run the `presubmit` target to format and run
+lint over the code. Fix any issues it indicates. When complete, send the pull
+request.
+
+```shell
+./gradlew presubmit
+```
+
+This target will reformat the code with
+[googleJavaFormat](https://github.com/sherter/google-java-format-gradle-plugin)
+and run lint. The lint report should open in your default browser.
