Suggestion: move articles to Github's repository's Wiki section

[mardab]

Dear mr. Lee,
For a while I was indecisive whether to PR indexed/cleaned up README.md file of this repository, akin to my previous work pulled in lupyuen/pinephone-nuttx#1 , given the fact, that this one contains much more pictures than code, and so even adding a small index to mark sections of it does not improve readability, searchability, and upkeep of its contents by a substantial amount, and rendering this file by itself is a non-trivial task for older and mobile devices, not to mention browsing it via Github's webpage.

I propose in my opinion a much more sustainable solution, and that would be to move those more in-detail articles to wiki section, which, being Markdown compatible and having an automated indexing of articles sounds like an easy to do and future-proof change, should the number and size of these articles grow even more.

Given that starting up and editing Wiki section requires elevated permissions, to be able to perform this myself, I have to ask you to create first page and decide on permissions model for this section first.
