 The virtual scroller has three main props:
 
 - `items` is the list of items you want to display in the scroller. There can be several types of item.
-- `renderers` is a map of component definitions objects or names for each item type. If you don't define `renderers`, the scroller will use *scoped slots* ([see below](#scoped-slots)).
 - `itemHeight` is the display height of the items in pixels used to calculate the scroll height and position.

+## Renderers
+
+The optional `renderers` prop is an object containing a component definition for each possible value of the item type. If you don't set this prop, [scoped slots](#scoped-slots) will be used instead. **The component definition must have an `item` prop, that will get the item object to render in the scroller.**
 
 There are additional props you can use:
 
 - `typeField` to customize which field is used on the items to get their type and use the corresponding definition in the `renderers` map. The default is `'type'`.
 - `keyField` to customize which field is used on the items to set their `key` special attribute (see [the documation](https://vuejs.org/v2/api/#key)). The default is `'id'`.
+
+## Scoped slots
+
+Alternatively, you can use [scoped slots](https://vuejs.org/v2/guide/components.html#Scoped-Slots) instead of `renderers`. This is active when you don't define the `renderers` prop on the virtual scroller.
+
+The scope will contain the row's item in the `item` attribute, so you can write `scope="props"` and then use `props.item`.
+
+Here is an example:
+
+```html
+<virtual-scroller class="scroller" :items="items" item-height="42" content-tag="table">
+  <template scope="props">
+    <tr v-if="props.item.type === 'letter'" class="letter">
+      <td>
+        {{props.item.value}} Scoped
+      </td>
+    </tr>
+
+    <tr v-if="props.item.type === 'person'" class="person">
+      <td>
+        {{props.item.value.name}}
+      </td>
+    </tr>
+  </template>
+</virtual-scroller>
+```
+
+## Customizing the tags
+
+These are optional props you can use to change the DOM tags used in the virtual scroller:
+
 - `mainTag` to change the DOM tag of the component root element. The default is `'div'`.
 - `containerTag` to change the DOM tag of the element simulating the height. The default is `'div'`.
 - `contentTag` to change the DOM tag of the element containing the items. The default is `'div'`. For example, you can change this to `'table'`.
