Moving documentation from wiki to forum

We are about to complete the move of our documentation from the wiki to the Documentation category of this forum.

As of a minute ago, all namespaces except for the Modules namespace (where the module pages in the wiki live) have been set to be read-only.

The next change, which I’m working on now, is to make the old wiki documentation URLs redirect to the corresponding forum pages—like we did with the Release Notes pages last year.

There’s not a 1:1 correspondence between old documentation pages in the wiki and new documentation pages here; therefore, we are not providing redirects at this time.
