This document discusses building REST APIs with Elixir and the Maru framework. It provides instructions on getting started with Maru, including adding it as a dependency and starting the Maru router. It then shows an example of building a REST API for users with Maru, including defining routes to get all users or a single user by ID, and filtering and sorting the results.
