+The `latest` branch in this repository is automatically maintained to be the last
+commit to `master` to pass all tests, in the same form found on npm. It is
+recommend to use builds deployed npm for many reasons, but if you want to use
+the latest not-yet-released version of parse-server, you can do so by depending
+directly on this branch:
+
+```
+npm install parseplatform/parse-server.git#latest
