# User-specific Modules¶

When the library antares is installed, some default treatments are made available to users. However, you can tell the library to look for your own treatments.

## Using Third-party Treatments¶

You can provide Antares with treatments that are not in the default path. Just setup the environment variable EXT_ANT_TREATMENT_PATHS.

EXT_ANT_TREATMENT_PATHS

path1:path2:path3

The files that implement treatments are prefixed by Treatment and suffixed by .py. All such files found in these previous paths will be loaded and made available in Antares.
