Thanks for working on Tor!

Slightly off-topic but do you have any pointer for someone who would like to help optimizing Tor? The current documents portal [1] has a big "OUTDATED" banner attached, and the WIP new portal contains too little information for me to make sense of how Tor works internally.

I worked on some areas of TBB before, but still feel like I don't know enough about Tor's internal.
