[REQ] Fill the wiki with content

[n4n0GH]

Describe the feature you'd like to see The wiki lacks in guides and info on what can be done with the settings of the hello components and where to find them. This needs to be addressed to create an easy to use knowledgebase for users.

Additional context Through many Issues and E-Mails it is very clear that there's a lack of knowledge when it comes to what can be done with the hello window decorations in particular.
