Hi Hugo,
I don't know if you noticed, but in the "libraries" section of the Wiki, I included listings of the functions that might need to have some documentation added. This was a carry over from an effort that started last year but that was never completed. If you're interested, it might help to add small blurbs in the wiki explaining what certain functions do just as you happen to come across them. Thanks for the work you've been doing!

Hello Ceyron,
I noticed. I'am not sure why there are both Sketch and Sketches pages.
May need merging.

I will not be able to complete docs further. Both because I have my French project to push forward and because I'am not an expert on chalktalk. Detailled documentations and definition of sketches needs pushes by your team members / experts, and recognition by your peers.

No problem! I just wanted to point it out in case you might be able to help with it.

Readme.md just cleaned up.
Doc is now on Wiki.
I close this issue. :D
