Editing Documentation and UI in Devstack

There are times when we want to make edx-platform in a running version of devstack our working GIT directory:

To build the developers documentation, we must be running the LMS and Studio, so the documentation can successfully pull in docstrings from Python code.
To edit UI strings in HTML templates and test immediately, we need to have the system running locally.

Install Devstack on your local system as described here.
Complete steps through vagrant up.
In Git for Mac, clone the repository to the devstack directory. You are overwriting the edx-platform directory with the repository from github.
Select your working branch and synch it.
Continue with instructions to run devstack.
You must use vagrant ssh into the box, then sudo su edxapp, then build the developers doc to get the docstrings.
You can also edit UI text and refresh the page to see changes.
Commit and synch changes in Git as you would otherwise.
