Making your own copy (fork) of Matplotlib#
You need to do this only once. The instructions here are very similar to the instructions at https://help.github.com/forking/ — please see that page for more detail. We're repeating some of it here just to give the specifics for the Matplotlib project, and to suggest some default names.
Set up and configure a github account#
If you don't have a github account, go to the github page, and make one.
You then need to configure your account to allow write access — see
Generating SSH keys help on github help.
