-There are lots of fancy depressionbot modules.
+Usage information for the modules included with depressionbot.
+
+## Quotes
+
+This is the original reason that DBot was created, stores and displays quotes.
+
+Commands:
+
+- _~q category_ - Display a random quote from a given category.
+- _~qadd category=newquote_ - Add a new quote to the database.
+- _~qstats_ - Show a list of the biggest quote categories.
+- _~qsearch category needle_ - Search for a quote in a given category.
+- _~rmlast [category]_ - Remove the last quote added to a given category, or the
+  last quote added.
+- _~rm category quote_ - Remove a given quote from the given category.
+- _~qcount category_ - Show the number of quotes stored in the given category.
+- _~rq_ - Show a random quote from a random category.
+- _~d_ - Show a quote from the category which matches the bot's name.
+- _~link category_ - Create a link to the page on the web interface which displays the
+  given category's quotes.
+- _~qprune_ - Delete empty quote categories.
+
+Unfortunately, this module is fairly highly coupled with certain other areas of
+the program. I am working on this, but note, for example, that one can still
+access quotes with the *~category* syntax even if the quotes module isn't
+loaded.
+
+## Admin
+
+Various administration functionality such as banning users, hot-reloading the 
+code and ordering him to talk. Note that commands added here are handled with
+their own listener, rather than being part of the command logic which is handled
+by the Command module. Functionality in this module can be slightly unsafe as
+not much error checking on the input is performed.
+
+TODO: Add summaries for each command in this module.
+
+## Spelling 
+
+Will attempt to correct a users' spelling by using the levenshtein distance
+algorithm. One corrects the spelling of their previous message by simply posting
+a message with their correction and an asterisk:
+
+    > user: I am a tutrle.
+    > user: *turtle
+    user meant: I am a turtle.
+
+The regular expression for this module also accepts two asterisks at the
+beginning of the correction, or at the end; it also accepts several words as the
+correction and deals with these fairly intelligently. Users may also attempt 
+to correct another users like so:
+
+    > userone: I am a tutrle.
+    > usertwo: userone: *turtle
+    > usertwo thinks userone meant: I am a turtle.
+
+
+## JS
+
+This module provides two commands which allow the execution of Javascript code.
+For regular users, there is the *~js* command, which is completely sandboxed,
+but can still be used for calculation and the like.
+
+    > ~js Array(16).join('wat'-1) + " Batman!";
+    'NaNNaNNaNNaNNaNNaNNaNNaNNaNNaNNaNNaNNaNNaNNaN Batman!'
+
+This feature is fairly safe as the user doesn't have access to anything
+dangerous, and is safe from infinite loops or locking DBot up because the code
+which is run is killed if it does not finish within a short amount of time.
+
+For administrators, the incredibly useful *~ajs* command is also available. The
+input for this command is simply 'eval'-ed and therefore has full access to
+DBot's memory. Of course, this is incredibly unsafe, but I find it rather fun;
+remember to only give extremely trusted friends administrator access to DBot, as
+there's nothing to stop them wiping the database or something similar - if
+you're worried about that kind of thing, do not load this module.
+
+However, it's useful for many things, such as administrative activity for 
+which there isn't a command in the admin module. For example, you could hot-add
+a new administrator like this:
+
+    > ~ajs dbot.admin.push('batman');
+    2
+
+You can also use this for debugging, or even adding new commands while DBot is
+running.
