 We have curated a [migration guide](2.0.0.md) that should help you migrate your code.
 
+## Want to ride the bleeding edge?
+
+We recommend using the most recent tagged build published to npm for production. However, you can test not-yet-released versions of the Parse-SDK-JS by referencing specific branches in your `package.json`. For example, to use the master branch:
+
+```
+npm install parse-community/Parse-SDK-JS.git#master
+```
+
+### Experimenting
+
+You can also use your own forks, and work in progress branches by specifying them:
+
+```
+npm install github:myUsername/Parse-SDK-JS#my-awesome-feature
+```
+
+And don't forget, if you plan to deploy it remotely, you should run `npm install` with the `--save` option.
+
+## Contributing
+
+We really want Parse to be yours, to see it grow and thrive in the open source community. Please see the [Contributing to Parse Javascript SDK guide](CONTRIBUTING.md).
