Documentation TODO

[martinfouilleul]

• Update the list of requirements
• Update the user tooling doc
• Split and update the dev tooling doc / building instructions to a separate document
• Update the cheat sheets
• Comment / write an accompanying tutorial file for each example
• "Getting Started" files (initially for C, later for other languages)
• Overview on our core data structures, eg arenas, strings, lists
• Canvas API documentation. In particular, the affine transform API and the text API might need some more in depth explanations.
• Setup the infrastructure for a standalone documentation website that we can fill in as we go
