I like to write notes whenever I want to learn something that I don't really understand or review something that I haven't used in a while. One never really knows what may be useful to others, and so I will make these notes available once I believe them to be sufficiently self-contained.

Since these are ultimately my own casually written notes, there may be some mistakes. Please feel free to reach out to me if you spot any.
