Task:Documentation rules

Imho it would be nice to have a small set of rules for editing documentation pages. Is there already a wiki page for this? If not, there should be one. E.g.: https://wiki.maemo.org/Documentation_rules

My first intension reading the first clean wiki article "Root access" was:
 * For which device?
 * For which OS?

In future artikles there will be the same questions. So in every documentation article of the wiki there should be some tags:
 * Testes with: N810
 * Tested with: 770
 * [...]
 * Tested with OS2006
 * [...]
 * Skills and requirements for doing the stuff written in this article

What do you think?
