+Smoke Testing UI
+----------------
+
+The `./tests` folder contains essential files to test our Custom Elements
+in isolation. As it is done for the `io-element` one, you need to add
+at least an `io-element.js` test file and its `io-element.html` related page.
+
+A package script entry such `"test:io-element.js"` should bundle the
+resulting page/component inside the `./smoke` folder.
+
+Please read how it's done for `io-element` to know more.

 Linting
 -------
 
 You can lint all options via `npm run lint`.
 
 You can also run specific target linting via `npm run lint:js` or, once available, via `npm run lint:css`.
 
 Remember, both `eslint` and `stylelint` can help fixing issues via `--fix` flag.
