 - `prevent(req, res, next)` Middleware that will bounce requests that happen faster than
                             the current wait time by calling `failCallback`. Equivilent to `getMiddleware(null)`
-- `getMiddleware(key)`      Generates middleware that will bounce requests with the same `key` and IP address
+- `getMiddleware(options)`  Generates middleware that will bounce requests with the same `key` and IP address
                             that happen faster than the current wait time by calling `failCallback`.
-                            `key` can be a string. Alternatively, key can be a `function(req, res, next)`
-                            that returns a string or calls `next`, passing a string as the first parameter.
                             Also attaches a function at `req.brute.reset` that can be called to reset the
                             counter for the current ip and key. This functions the the `reset` instance method,
                             but without the need to explicitly pass the `ip` and `key` paramters

+	- `failCallback`  Allows you to override the value of `failCallback` for this middleware
 - `reset(ip, key, next)`    Resets the wait time between requests back to its initial value. You can pass `null`
                             for `key` if you want to reset a request protected by `protect`.
 - `getIPFromRequest(req)`   Uses the current proxy trust settings to get the current IP from a request object
