Here are some ideas that I think work better:
- 15 repetitions of "React". Removed a few.
- The "two main ideas" weren't clearly separated. I put them under different headers and simplified the wording.
- The "Give it Five Minutes section didn't sound as reassuring. Made it sound more certain.
This will let us keep docs in order on the filesystem but have
reasonable permalinks. If we add something at 02- it doesn't result in
lots of broken links.
