Be warned that the state of docs is very weak, and that although the Solid team acknowledges this issue and are working on a beta¹ version of the docs, the effort really crawls along. It's also really hard to get help. Maybe there are many Solid lovers, but there aren't enough Solid intermediates to help prune the support forum. I attribute this to slow progress of the docs.

[1]: Note that this docs effort doesn't include SolidStart, which is a big bummer.
