This contains a lot of valuable information about how Solid works. Nice job. However, I'm uncertain if it aligns well with our docs. Even in the advanced section, I think it's too technical to be useful to most people.

The section on Hyperscript is helpful for those who want to use Solid without a build step (there's an issue regarding this), but I would prefer to have a more practical guide about it.

If we had a blog, I would share this information there, as it would be a shame to lose it. Especially the information about custom renderers is interesting. Overall, I don't think this is a good fit for our docs.
