-# Description
-
-This role configures a Systemd timer that periodically purges the Nimbus node database to test the sync process. Optionally it can use the [trusted node sync](https://nimbus.guide/trusted-node-sync.html) functionality.
-
-# Configuration
-
-In order to purge database of `beacon-node-mainnet-stable` weekly and sync it from trusted node:
-```yaml
-nimbus_db_purge_node_service_name: 'beacon-node-mainnet-stable'
-nimbus_db_purge_node_service_path: '/data/{{ nimbus_db_purge_node_service_name }}'
-nimbus_db_purge_node_network_name: 'mainnet'
-nimbus_db_purge_timer_frequency: 'weekly'
-nimbus_db_purge_truster_node_api_url: 'http://localhost:9300'
-nimbus_db_purge_trusted_node_sync_enabled: true
-```
-
-# Management
-
-The Systemd timer can be managed with `systemctl`:
-```
- > sudo systemctl -o cat status purge-beacon-node-mainnet-stable
-● purge-beacon-node-mainnet-stable.service - Purge beacon-node-mainnet-stable DB
