-If you'd like to preview your documentation changes, first commit your changes to your local 3.6.x branch, then execute `make docs` from the project root, which switches to the gh-pages branch, merges from the 3.6.x branch and builds all the static pages for you. Now execute `node static.js` from the project root which will launch a local webserver where you can browse the documentation site locally. If all looks good, submit a [pull request](https://help.github.com/articles/using-pull-requests/) to the 3.6.x branch with your changes.
