TODO:

Write the foreword from the compiler. (among other things) discuss the lineage of this project (steal from my releases page summaries?), discuss how this is Version 1 as opposed to Amazon's Version 2 (sub-version-1 changes can be found tracked in https://github.com/florolf/unsong-scrape), also give a shout out to unsong-scraper which is a lot like this project but in ruby, also https://github.com/darioml/unsong-scraper-node seems a lot like the same but in javascript. Uhhh make a cover image in yellow and a title page in white. Possibly add this readme as a foreword? possibly talk about the v1–v2 changes in some detail, possibly doing a diff on my end if i can get the files (although I will not share the per se files or diff, for obvious reasons).
