 ### Using Agents and Commands
 
-WIP
+A `COMMANDS` map is exported which lets you get a command from the above list for the detected agent. For example:
+```
+import { detect } from 'package-manager-detector'
+import { COMMANDS } from 'package-manager-detector/agents'
+
+const pm = await detect()
+if (!pm) throw new Error('Could not detect package manager')
+
+const command = COMMANDS[pm.agent]['frozen']
+console.log(`Detected the ${pm.agent} package manager. You can run a frozen install with ${command}`);
+```
