+## Creating a plugin
+
+Please consult a **noobie.schema.json** for details. Below are few important excerpts:
+
+- `icon` of the widget or menu item can be one of 
+  - a name of feathericons icon, you can get it here: [feathericons.com](https://feathericons.com/); 
+  - an absolute path to the image file;
+  - URL to the image file. If you are not sure image exists, you can add a `icon_fallback` field with an absolute path to the fallback image;
+ - for a horizontal line in the menu add an item with title equals to '-', like  
+    ```json
+    { "title":  "-" }
+    ```
+  - for a header menu item set `header` field to true, note that the `icon` field will be ignored:
+    ```json
+    {
+      "header": "true",
+      "title": "Header Title"
+    }
+    ```
