Introduce yourself to Git:
git config --global user.email firstname.lastname@example.org git config --global user.name "Your Name Comes Here"
You need to do this only once. The instructions here are very similar to the instructions at http://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 NumPy project, and to suggest some default names.
You then need to configure your account to allow write access - see the Generating SSH keys help on github help.
First you follow the instructions for Making your own copy (fork) of NumPy.
git clone email@example.com:your-user-name/numpy.git cd numpy git remote add upstream git://github.com/numpy/numpy.git
Clone your fork to the local computer with git clone firstname.lastname@example.org:your-user-name/numpy.git
Investigate. Change directory to your new repo: cd numpy. Then git branch -a to show you all branches. You’ll get something like:
* master remotes/origin/master
This tells you that you are currently on the master branch, and that you also have a remote connection to origin/master. What remote repository is remote/origin? Try git remote -v to see the URLs for the remote. They will point to your github fork.
Now you want to connect to the upstream NumPy github repository, so you can merge in changes from trunk.
