making-of available

To use when the generating process of the post is available somewhere, whether uploaded on aibooru as a making-of, present in the artist commentary as a video link (to youtube, for example), or available in some other way somewhere (in which case it should be indicated with a link in the comments).

If the picture itself details the "making of" (such as with post #38919), use the making-of or how to tags instead.
