I was having trouble getting the pole vector to work on the arms and legs due to their positioning, I used this video to resolve the issue: https://www.youtube.com/watch?v=GxM4GawKwjQ
I found the rigging process was a lot to take in so I made notes that I would be able to refer back to. This helped me process the recorded lecture and allowed me to double check shortcuts without rewatching or finding a specific place in the video.
