+## Configuration
+
+Master Cut recive requests from diferent Quota Scraper services, and each one is part of a group. For example, group `Trabajadores` have two Quota Scraper services, one per server, and shares the CUT file. So we need to tell to Master Cut what groups exists, and CUT file and script. For that, we use JSON configuration like that:
+
+```json
+{
+    "groups": [
+        {
+            "name": "trabajadores",
+            "file": "trabajadores.cut",
+            "script": "trabajadores.sh"
+        }
+    ]
+}
+```
+
+Configuration path is set with argument `--conf`.
