-`:CocConfig`
+The configuration can be added directly to coc-settings (`:CocConfig`) like the following:
 
 ```json
-"languageserver": {
-  "perlnavigator": {
-    "command": "node",
-    "args": [
-      "/path/to/PerlNavigator/server/out/server.js",
-      "--stdio"
-    ],
-    "filetypes": ["perl"]

+        "--stdio"
+      ],
+      "filetypes": ["perl"]
+    }
   }

+}
