 ### Synchronize With URL
 
-When a List based component (eg: `PostList`) is passed to the `list` prop of a `<Resource>`, it will automatically synchronize its parameters with the browser URL (using react-router location). However, when used anywhere outside a `<Resource>`, it won't synchronize, which can be useful when you have multiple lists on a single page for example.
+When a `<List>` based component (eg: `<PostList>`) is passed as a `<Resource list>`, react-admin synchronizes its parameters (sort, pagination, filters) with the query string in the URL (using `react-router` location). It does so by setting the `<List syncWithLocation>` prop by default.
 
-In order to enable the synchronization with the URL, you can set the `syncWithLocation` prop. For example, adding a `List` to an `Edit` page:
+When you use a `<List>` component anywhere else than as `<Resource list>`, `syncWithLocation` isn't enabled, and so `<List>` doesn't synchronize its parameters with the URL - the `<List>` parameters are kept in a local state, independent for each `<List>` instance. This allows to have multiple lists on a single page. The drawback is that a hit on the "back" button doesn't restore the previous list parameters.
+
+You may, however, wish to enable `syncWithLocation` on a `<List>` component that is not a `<Resource list>`. For instance, you may want to display a `<List>` of Posts in a Dashboard, and allow users to use the "back" button to undo a sort, pagination, or filter change on that list. In such cases, set the `syncWithLocation` prop to `true`:
