 ```
 
-#### module([options](#options))
+### module([options](#options))
 
 Initialize the Redis connection with the optionally provided options (see above). _The variable `session` below references this_.
 
-#### session.get(sid)
+### session.get(sid)
 
 Generator that gets a session by ID. Returns parsed JSON is exists, `null` if it does not exist, and nothing upon error.
 
-#### session.set(sid, sess, ttl)
+### session.set(sid, sess, ttl)
 
 Generator that sets a JSON session by ID with an optional time-to-live (ttl) in milliseconds. Yields `ioredis`'s `client.set()` or `client.setex()`.
 
-#### session.destroy(sid)
+### session.destroy(sid)
 
 Generator that destroys a session (removes it from Redis) by ID. Tields `ioredis`'s `client.del()`.
 
-#### session.quit()
+### session.quit()
 
 Generator that stops a Redis session after everything in the queue has completed. Yields `ioredis`'s `client.quit()`.
 
-#### session.end()
+### session.end()
 
 Alias to `session.quit()`. It is not safe to use the real end function, as it cuts off the queue.
 
-#### session.connected
+### session.connected
 
 Boolean giving the connection status updated using `client.connected` after any of the events above is fired.
 
-#### session.\_redisClient
+### session.\_redisClient
 
 Direct access to the `ioredis` client object.
 
-#### session.client
+### session.client
 
 Direct access to the `co-redis` wrapper around the `ioredis` client.
