 The example below illustrates how to create a Plugin Config and bind it to a Route:
 
-    ```shell
-    curl http://127.0.0.1:9180/apisix/admin/plugin_configs/1 \
-    -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -i -d '
-    {
-        "desc": "blah",
-        "plugins": {
-            "limit-count": {
-                "count": 2,
-                "time_window": 60,
-                "rejected_code": 503
-            }
+```shell

+-H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -i -d '

         }
-    }'

-            }
+    }

+-H 'X-API-KEY:edd1c9f034335f136f87ad84b625c8f1' -X PUT -i -d '

         }
-    }'
-    ```
+    }
+}'

 When APISIX can't find the Plugin Config with the `id`, the requests reaching this Route are terminated with a status code of `503`.
