I went as suggested to wiki pages, but I think I am still not used to its interface. Made a short gotcha add there for a test and now think how people will find it, it doesn't appear anywhere, where is a chance someone will look for it

On the other hand, I still don't think clogging main page with installation by little notes with version differencies will appropriate

Is there a way at least to show "talk" comments added to the bottom of the main page, like comments in geeklog, or, may be have significant ones as sub-pages, under the main page?
