There needs to be some discussion on what material we want to share. For example, originally, I had live coding scripts for me alone, then I just had bullets with the main points, however latterly I've been trying to write them as walkthroughs that a student could go through again at their own pace if needs be. So my direct reuse of "master" materials has been limited. Rather I pick and choose bits of those. And then just reuse my walkthroughs on subsequent boot camps, as it cuts down on preparation time.
