+A simple example for `use_element_hover`.
+
+If you don't have it installed already, install [Trunk](https://trunkrs.dev/) and [Tailwind](https://tailwindcss.com/docs/installation)
+as well as the nightly toolchain for Rust and the wasm32-unknown-unknown target:
+
+```bash
+cargo install trunk
+npm install -D tailwindcss @tailwindcss/forms
+rustup toolchain install nightly
+rustup target add wasm32-unknown-unknown
+```
+
+Then, open two terminals. In the first one, run:
+
+```
+npx tailwindcss -i ./input.css -o ./style/output.css --watch
+```
+
+In the second one, run:
+
+```bash
+trunk serve --open
+```
