 ## Usage
 
-* The [`generate_types`] macro allows you to generate structs based on your [input query]. It will also generate output/response types for the current Function API, based on the provided schema.
-    * It will automatically generate an `.output.graphql` file for code generation purposes. This file can be added to your `.gitignore`.
-* The [`shopify_function`] attribute macro marks the following function as the entry point for a Shopify Function. It manages the Functions `STDIN` input parsing and `STDOUT` output serialization for you.
-* The [`run_function_with_input`] function is a utility for unit testing which allows you to quickly add new tests based on a given JSON input string.
