Git: Maybe encourage teachers to draw ad-hoc diagrams

[illicitonion]

Which module(s) and week(s) does this change effect?
Module(s): Git
Week(s): Week 1

When @frosas taught this module recently, he found it was useful to himself be drawing up the stages of the git workflow in a diagram piece by piece - the act of drawing, and the act of adding pieces when introducing the topics, helped to visualise what was going on, and directly relate the concept with the diagram.

We should work out if there's a nice way to encourage this (IRL we'd just say "draw on a whiteboard as you go along", but online it's harder - tablets would be amazing, but ASCII art, or a paint-like environment would do... There's probably a bigger discussion to have here around remote class diagramming...)

I like having the option for teachers to draw interactively, but this might be complicated by having to communicate this to many teachers.

A simple cover-all strategy might be to split our existing (& future) diagrams into pieces. These can then be revealed progressively (scrolling through the syllabus, or providing mechanism for revealing the next diagram, or by showing them over multiple slides). This still leaves the door open to do interactive drawing if wanted.
