+# Usage
 
 The examples in this README use the [Splines Demo API](https://github.com/ruby-grape/grape-with-roar) running [here](https://grape-with-roar.herokuapp.com/api). If you're upgrading from a previous version, please make sure to read [UPGRADING](UPGRADING.md).

-### Links and Embedded Resources
+## Links and Embedded Resources
 
 The splines example above followed a link called "splines". While you can, you do not need to specify the HAL navigational structure, including links or embedded resources. Hyperclient will resolve these for you.  If you prefer, you can explicitly navigate the link structure via `_links`. In the following example the "splines" link leads to a collection of embedded splines. Invoking `api.splines` is equivalent to `api._links.splines._embedded.splines`.
 
 ```ruby
 api._links.splines
 ```
 
-### Templated Links
+## Templated Links
 
 Templated links require variables to be expanded. For example, the demo API has a link called "spline" that requires a spline "uuid".

 The client is responsible for supplying all the necessary parameters. Templated links don't do any strict parameter name checking and don't support required vs. optional parameters. Parameters not declared by the API will be dropped and will not have any effect when passed to `_expand`.
