   * Use an inline module: `<script type="module">`
-    * Note: `me()` will no longer see `parentElement` so explicit selectors are required: `me(".mybutton")`
+    * Warning: When using a module `me()` can no longer see `parentElement`, this means explicit selectors are required: `me(".mybutton")`
 
 #### Select a void element like `<input type="text" />`
 * Use: `me('-')` or `me('prev')` or `me('previous')`
