You're right, the instructions are scattered around the different type of relation and so not easily found. They're also not (generally) written with the newbie in mind, so not easily understood. But the problem is that the different types of OSM relation, like your real-life relations, are all different, do different things and behave somewhat differently. What you're asking for is similar to the job interview question "Describe yourself in a single word" (my answer is "indescribable") except it's closer "Describe all your relatives in a single word" (my answer is "related"). Oh, and never forget that this is OSM. So you'll find one person saying that relations of type A, B and C are not only valid but also vital whilst any other type of relation is an abomination and another person saying types A, B and C are unnecessary abominations and all other types are valid and essential. For example, super relations solve several distinct problems and are, at the same time, an unnecessary abomination with no conceivable use cases (I thought of a nifty use for them that would be useful to me but they are so despised by so many people I'm scared of even mentioning it). Right now I can't think of a way of improving the documentation in the way you (and I) would like because the relation types differ so much. All that comes to mind is a page saying that "relations relate things" with a list of the different types and a one-line description. -- Paul
