+## Using Genqlient with the Red Hat Ecosystem Catalog
+
+This directory contains the necessary files to generate a type-safe Go GraphQL client for the Red Hat Ecosystem Catalog using [genqlient](https://github.com/Khan/genqlient).
+
+### File Structure
+
+-   `genqlient.yaml`: The configuration file for `genqlient`. It specifies the location of the GraphQL schema, the directory containing the GraphQL queries, and the output file for the generated code.
+-   `queries/`: This directory contains the GraphQL schema and query files.
+    -   `schema.graphql`: The GraphQL schema for the Red Hat Ecosystem Catalog API.
+    -   `*.graphql`: Files containing the GraphQL queries.
+
+### Generating the Client
+
+To regenerate the client, you will first need to ensure the required tools are installed by running `make deps` from the project root. Once the tools are installed, you can generate the client by running the following command from the `catalog` directory:
+
+```bash
+make gen/graphql
+```
+
+This will generate the `generated.go` file in the current directory.
+
+### Downloading the Schema
+
+The `schema.graphql` file can be updated by downloading the latest version from the Red Hat Ecosystem Catalog API. You can do this by running the following command from the `catalog` directory:
+
+```bash
+make download/graphql-schema
+```
+
+This will download the schema and save it to the correct location. After updating the schema, you should regenerate the client to ensure it is up to date.
