This guide offers the least time-consuming way of setting up Nginx for serving Git repositories over HTTP using Gitweb. The stuff here has been tested with Git 1.9.1 and Nginx 1.6.0 on Debian Wheezy. Probably also works for Ubuntu, etc.

Total time ~ 10 minutes.

Install

Enable wheezy-backports by adding this line to /etc/apt/sources.list:

deb http://http.debian.net/debian wheezy-backports main

• User cases (description of sequences of events that, taken together, lead to a system doing something useful)
  • Who is going to use it?
  • How are they going to use it?
