+### Two-way Binding
+
+One caveat is there's currently [no support for v-model on custom elements](https://github.com/vuejs/vue/issues/7830), but you can still achieve two-way binding manually.
+
+```html
+<!-- This doesn't work -->
+<sl-input v-model="name"></sl-input>
+<!-- This works, but it's a bit longer -->
+<sl-input :value="name" @input="name = $event.target.value"></sl-input>
+```
+
+If that's too verbose for your liking, you can use a custom directive instead. [This utility](https://www.npmjs.com/package/@shoelace-style/vue-sl-model) adds a custom directive that will work just like `v-model` but for Shoelace components.
