You can automaticallly download the latest public indicator files with the command `mvt-ios download-iocs` or `mvt-android download-iocs`. These commands download the list of indicators listed [here](https://github.com/mvt-project/mvt/blob/main/public_indicators.json) and store them in the [appdir](https://pypi.org/project/appdirs/) folder. They are then loaded automatically by mvt.
