We already have quite a few nice [tags](https://german.stackexchange.com/tags) for classifying questions to make them better searchable.

But not all of them have a tag wiki, and some existing tag wikis are not really good. There is still some work to be done and 2 reputation to be earned for users who have not yet gained the [Trusted User privilege](https://german.stackexchange.com/help/privileges/trusted-user).

What format do we want the tag wikis to be in? Which information should be displayed when hovering over the tag or selecting a tag on creating a question?
