First and important rule on our Wiki: Clarity.
All basic info of module on top. As short as possible. Code can explain itself enough, if not: user should know where to look for information.
Basic info on top. Same format!
Clarity, as for editor like for Users.
Short Description : One short sentence. If user would like to know more, can click a link and check what's is inside with more explanation.
Any references to anything out of module should be separated. Clarity for other Editors.
