+Note: __README.md__ is generated from comments in __index.js__. Do not modify
+__README.md__ directly.
+
+1.  Update local master branch:
+
+        $ git checkout master
+        $ git pull upstream master
+
+2.  Create feature branch:
+
+        $ git checkout -b feature-x
+
+3.  Make one or more atomic commits, and ensure that each commit has a
+    descriptive commit message. Commit messages should be line wrapped
+    at 72 characters.
+
+4.  Run `make test lint`, and address any errors. Preferably, fix commits
+    in place using `git rebase` or `git commit --amend` to make the changes
+    easier to review.
+
+5.  Push:
+
+        $ git push origin feature-x
+
+6.  Open a pull request.
