 React-admin provides one hook for each of the Data Provider methods. They are useful shortcuts that make your code more readable and more robust.
 
+The query hooks execute on mount. They return an object with the following properties: `{ data, isLoading, error }`. Query hooks are:
+
+* [`useGetList`](./useGetList.md)
+* [`useGetOne`](./useGetOne.md)
+* [`useGetMany`](./useGetMany.md)
+* [`useGetManyReference`](./useGetManyReference.md)
+
+The mutation hooks execute the query when you call a callback. They return an array with the following items: `[mutate, { data, isLoading, error }]`. Mutation hooks are:
+
+* [`useCreate`](./useCreate.md)
+* [`useUpdate`](./useUpdate.md)
+* [`useUpdateMany`](./useUpdateMany.md)
+* [`useDelete`](./useDelete.md)
+* [`useDeleteMany`](./useDeleteMany.md)

 ## `meta` Parameter
 
 All Data Provider methods accept a `meta` parameter. React-admin doesn't set this parameter by default in its queries, but it's a good way to pass special arguments or metadata to an API call.
