+One thing to note on this is that it currently only supports unique tags, unless you use the `keyOverride` prop to provide a unique [key](https://reactjs.org/docs/lists-and-keys.html#keys) to each additional meta tag.
 
-Example:
+The default behaviour (without a `keyOverride` prop) is to render one tag per unique `name` / `property` / `httpEquiv`. The last one defined will be rendered.
