 ## [Unreleased]
 
+### Added
+
+- **BREAKING:** new (auto-)init behaviour, inspired by [petite-vue](https://github.com/vuejs/petite-vue)
+  - `require`, `import`, or use `<script>` to include Shareon without
+    initialization
+  - use exported `initializeShareon` function in Node to initialize Shareon
+  - use `init` attribute in `script` to initialize Shareon in-browser
+
+    ```html
+    <script src="path/to/shareon.js" init>
+    ```
+
