Gatsby JS and MDX
I'm a fan of nice documentation. You know the kind: it has the right examples for all the complicated stuff, sane organization of all the topics, and isn't just an autogenerated list of all the function names or API actions. Solid documentation is one of those rare vintages that you slowly imbibe and learn every nuance and tasting note of it. I'm sure I'm not the only one, you can confide in me (and the Internet). I'm going to let my documentation freak flag fly high and proud!
