 You can combine arguments, for example `--id 123 --clear`
 
+### Multiple IDs
+
+You can pass multiple App IDs in two ways:
+
+```bash
+# Comma-separated
+sau --id 123,456,789
+
+# Multiple --id flags
+sau --id 123 --id 456 --id 789
+```
+
 To find an App ID, search for the game on [SteamDB](https://steamdb.info/) or check the game's Steam store page URL.
