Projects / New Projects - Give option of importing Github README files into C4P project description

As as Code for Philly organizer, I want to make it easy as possible to create & maintain projects on cfp.org, so that project entries are kept fresh.

Providing project managers the opportunity to upload / actively link a previously written README or CONTRIBUTING file directly from GitHub into their project's code4philly.org readme.md section would reduce the admin overhead involved in keeping both places current/fresh.
