-# Gatekeeper Filter
-
-# Overview
-
-This filter will learn from input data read during a learning phase. After
-learning the characteristics of the input, the filter can then be set into
-the enforcing mode. In this mode the filter will block any queries that do
-not conform to the training set. This is a simple yet effective way to prevent
-unwanted queries from being executed in the database.
-
-When the filter receives a query in the learning mode, the filter converts it
-into a canonicalized form i.e. creates a query digest. The query digest is then
-stored for later use.
-
-When the filter is started in enforcing mode, the list of stored query digests
-is used as a master list of allowed queries. The filter calculates a query
-digest for all incoming queries and compares it to the master list. If the
-query digest is in the master list, the query is executed normally. If it
-isn't found from the list, the query is not executed, an error is returned
-to the client and a warning message is logged.

-# Configuration
-
-## Filter Parameters
-
-### `mode`
-
-This is a mandatory parameter for the filter which controls the filter's operation.
-
-Accepted values are _learn_ and _enforce_. _learn_ sets the filter into the
-learning mode, where the query digests are calculated and stored at the end of
-each session. _enforce_ sets the filter into the enforcement mode where incoming
-queries are compared to the previously calculated list of query digests.
-
-### `datadir`
-
-This is an optional parameter which controls where the calculated query digests
-are stored. This parameter takes an absolute path to a directory as its argument.
-
-## Example Configuration
-
-Here is an example configuration of the filter with both the mandatory _mode_
-and the optional _datadir_ parameters defined. The filter is in learning mode
-and after collecting enough samples, the filter is should be set into enforcing
-mode. The filter stores the gathered query digests in `/var/lib/maxscale/gatekeeper/`.
