# Adding configuration to a Module

## The trade-off between re-usability and usability

The more general the interface, the greater the re-usability, but it is then more complex and hence less usable.

It is often good to find a compromise by means of configuration.

## Module configuration

The default configuration is placed in local/plugins/Name/config.yaml.

parameters:
name:
setting: 42


A user can override this configuration in social.local.yaml with:

parameters:
locals:
name:
setting: 1337


Note that if plugin's name is something like FirstSecond, it will become first_second in the configuration file.
