[WIP] Proof of concept - Make the docs part of the Gatsby website

[lindapaiste]

This is something I'm playing around with. I don't know if it makes sense to do this. Docsify has some nice features (search and sidebar) but also some limitations.

I did:

• Copy .md files from docsify repo
• Add "frontmatter" to some .md files, specifying the URL path and title
• Get Gatsby to load these files as pages (There's a mix of two approaches right now, where one works for some pages but not others)

I did not:

• Copy the CSS styles from Docsify
• Recreate the Docsify sidebar
• Implement a search feature
• Embed images and iframes
• Add frontmatter to every page
