+# Configuration
+
+Judge Agent should be a valid CodeForces account.
+
+We highly recommend **5~10 Judge Agents** enabled for CodeForces Gym NOJ Babel Extension.
+
+Set username the handle and password the password from CodeForces.
+
+**Setting email as handle will break some features like `babel:judge`.**
+

+# FAQs
+
+**Q:** Can I use the same agent from my codeforces extension?
+
+**A:** You **CAN**, but you **shouldn't**. Because CodeForces has rate limit for accounts, having 2 separated extension sharing the same rate limit pool is not best practise for maintenance. For having different sets of judge agents for CodeForces and CodeForces Gym, you can controll them separately. But if you want to set them the same, it is totally fine and workable.
