QBot features documentations in Discord itself. This is named 'QBot Dictionary', as it's basically a dictionary of features and terms used by QBot. The list includes more than a hundred features and terms you can search for, then select the term you want to view the definition of.
QDictionary [SearchQuery] or QD [SearchQuery]
When you searched for something and it isn't a direct hit, you will be prompted with search results. Query will automatically pick the best matching
result, but you can still choose from a list of results. Use the numbers '1' through '5' to pick a term, and QBot will display the definition of that term.
If there is only one result of your search, send the number '1' and QBot will display that result.
