+## Protocol
 
 The protocols supported by MaxScale are implemented as external modules that are loaded dynamically into the MaxScale core. These modules reside in the directory `/usr/lib64/maxscale`. The location can be overridden with the `libdir=PATH` parameter under the `[maxscale]` section. It may also be set by passing the `-B PATH` or `--libdir=PATH` option on the MaxScale command line.
