##what is a tag wiki? Tag wikis are brief excerpts of information detailing what the tag is about, the kinds of questions that should be asked in a tag, and possibly providing you links to some external resources like the Wikipedia article or official website for whatever the tag is about. (if applicable) ##what makes a good tag wiki? Clear, concise and original information. Tag wikis are shown in multiple places as follows: When you hover over a tag, either in the tag list, or on a question, a nice little pop up will appear detailing the Excerpt section from the tag wiki: >![enter image description here][2] This same excerpt is displayed at the top of the list of questions when you're browsing questions by tag, with a link to "learn more": >![enter image description here][3] The full tag wiki is displayed when you click "learn more": >![enter image description here][4] So, a good tag wiki will: - Concisely state what the tag is about when you hover over a tag - Give a full description of what the tag is when you click "learn more" - Detail where you can find more information when you click "learn more" - Be original - we don't like plagiarism at the best of times, but on tag wikis, **don't do it**. If you want to include a small section of text from a site like Wikipedia, clearly block quote it and attribute it and ensure it's not the only information present in the tag. Tag wikis should be started using the dictionary method; that is we make the assumption that the user knows what they've just clicked on, so don't reiterate it. This means instead of > "Minecraft is a game by Mojang where you break blocks and eat cake" we use > "A game by Mojang where you break blocks and eat cake" #what tags need a tag wiki adding?
