 ## About
 
-Custom MongoDB Docker image extending `mongo:latest` with automated backups, retention management, and replica set configuration.
+Custom MongoDB Docker image extending `mongo:latest` with automated backup functionality. 
 
-Includes cron-based scheduled `mongodump` operations with compression, automatic stale lock recovery on unclean shutdowns, and zero-config replica set initialization — while preserving all native MongoDB functionality.
+Installs cron to run scheduled mongodump operations with compression and retention management, while preserving all native MongoDB server functionality.
 
-**Manually trigger a backup:**
+Backups can be manually triggered with: `docker --exec -t mongodb backup`
-docker exec -t mongodb backup
 
-**Restore a backup:**
+To restore a backup, uncompress it and use the official `mongorestore`
-Decompress the archive and use the official `mongorestore` tool.
