# Configuration

Authelia is highly configurable thanks to a configuration file. 
There is a documented template configuration, called
[config.template.yml](../config.template.yml), at the root of the
repository. All the details are documented there.

When running **Authelia**, you can specify your configuration file by passing
the file path as the first argument of **Authelia**.

    $ authelia --config config.custom.yml
