These are the instructions if you just want to follow the latest scikit-image source, but you don’t need to do any development for now.
The steps are:
From the command line:
git clone git://github.com/scikit-image/scikit-image.git
You now have a copy of the code tree in the new scikit-image directory.
From time to time you may want to pull down the latest code. Do this with:
cd scikit-image
git pull
The tree in scikit-image will now have the latest changes from the initial repository.
