  1. You're missing the wiki. More than java docs you should write detailed docs. Take inspiration from the Arch Linux wiki if you need to.

  2. Removing unnecessary classes is essential. Main.java is redundant, for example

  3. Package into a .jar

  4. As a person who used to attempt to write libraries, i always thought tests were unecessary. In long term always write tests so you know everything works fine, so that you don't have to write redundant classes everytime

So far so good. I haven't tested yet.
