Build a mind map outline for a topic

Task: Build a mind map outline for [topic] that I can type straight into a mind map tool. Context: I am making it for [purpose, such as studying, a talk or brainstorming] and I already know [what I already know about the topic]. Skip what I already know unless a branch needs it. Rules: - Use one center, exactly five branches and at most three sub-branches per branch. - Keep every label to four words or fewer, using nouns or short verb phrases. - Order the branches in the sequence I would learn or present them. - Add facts, dates and names only as placeholders such as "[key date]" for me to fill in. Result: An indented list with the center on the first line, branches at one level and sub-branches at two levels. After it, one sentence on which branch to expand first.
