This is the official repository for UltiSnips on GitHub. It is held in sync with the official bzr repository over at Launchpad  and is meant as a convenience for contributors. Send Pull request to this repository, not the automatic clone from vim-scripts.
Note that we do not use the Issue tracker here on GitHub because the one on Launchpad is superior and already has a significant history. Please report issues over there.
The blog posts of the screencasts contain more advanced examples of the things discussed in the video.
