I would recommend condensing the information you want to share as much as possible. If you’re coming close to a post limit, you’re writing too much. People won’t read 15 paragraphs on a concept for a tool.
If need be, use diagrams or, better yet, reference similar tools or technologies which exist already as examples. This shows you’re aware of the ecosystem and have validated your ideas.
I look forward to reading your thoughts about code documentation.
