+# RomM Guest
+
+Deploy a dedicated RomM guest on Pikachu with Nixpkgs RomM 5.2.0.
+
+Follow the standard guest-provisioning protocol.
+Keep the old installation's public domain.
+
+Use the local PostgreSQL and Redis instances from `services.romm`.
+Set guest limits to `4G` memory, `200%` CPU, and `512` tasks.
+Enable the library watcher.
+Use RomM built-in accounts.
+
+Mount persistent application data:
+
+```text
+/pikachu/data/romm             -> /var/lib/romm
+/pikachu/data/romm/postgresql  -> /var/lib/postgresql
+/pikachu/data/romm/redis       -> /var/lib/redis-romm
+```
+
+Mount browsable media:
+
+```text
+/pikachu/media/games/emulation/roms  -> /var/lib/romm/library/roms
+/pikachu/media/games/emulation/bios  -> /var/lib/romm/library/bios
+/pikachu/media/games/emulation/users -> /var/lib/romm/assets/users
+```
+
+Configure IGDB, ScreenScraper, and SteamGridDB from secrets.
+Use RomM's default metadata, artwork, region, and language priorities.
