no wiki, poor documentation, little community [closed]

Hi, i have big pain to find any didactic and useful information around lgi and also goo canvas and all that is over.
Can you link some nice references to help dev users to win a bit of time to learn how to use this ?
Maybe there is something usefull to do on this point, i really would like to help on that, but... i feel myself locked and stick with my miss-understanding of lgi, and GooCanvas and GTK and Cairo all around.
I just arrived with help to build 3 rectangle's shapes and handle mouse event (and, because of big help, if not, i would never be able in this year to just do that, even if i know to use other GUI, not only wrappers around also) then build a collid test who miserably failed because of, i think, a bad event managment (not from lgi, but from myself, because i not really understand what i have to do to fix the problem as long as the lgi and gtk and cairo and goo canvas doc is poor and example also with mouse event and canvas especialy).
What do you think about that ? Any plan to ask dev to help make something useful for information around ?

Start by reviewing the existing lgi documentation and examples alongside the GooCanvas, GTK, and Cairo references mentioned in the issue. Done should provide useful, didactic guidance for developers, especially around canvas usage, mouse events, and collision handling.
