ForkingInstructions.md

1. Fork a repository (http://github.com/zendframework/zf1)
2. Clone your fork locally and enter it (use your own GitHub username in the statement below)

% git clone git@github.com:<username>/zf1.git
% cd zf1

3. Add a remote to the canonical repository, so you can keep your fork up-to-date:

% git remote add zf1 https://github.com/zendframework/zf1.git
% git fetch zf1
