+  <p align="center">A GitHub Action that uploads your OpenAPI specifications to Hey API 🚀</p>
+</div>
 
-This action will upload your OpenAPI specification to Hey API.
+To use this action, you have to be registered with [Hey API](https://heyapi.vercel.app/). If you don't have an account, please [email us](mailto:[email protected]) or [open an issue](https://github.com/hey-api/upload-openapi-spec/issues) and we will set you up.
+
+## Usage
+
+Create a new GitHub workflow or add an upload step to your existing workflow inside your API codebase.
+
+```yaml
+name: Upload OpenAPI Specification
+
+on:
+  push:
+    branches:
+      - main
+
+jobs:
+  upload-openapi-spec:
+    runs-on: ubuntu-latest
+    steps:
+      - name: Checkout
+        uses: actions/checkout@v4
+
+      - name: Upload OpenAPI spec
+        uses: hey-api/upload-openapi-spec@v1
+        with:
+          hey-api-token: ${{ secrets.HEY_API_TOKEN }}
+          path-to-openapi: path/to/openapi.json
+```
+
+The example above will send your OpenAPI spec to Hey API on every push to `main` branch.
+
+## Inputs
+
+To successfully upload an OpenAPI specification, you need to provide the following inputs (see `with` in the example above)
+
+### `hey-api-token`
+
+This is the authorization token you obtained from us.
+
+### `path-to-openapi`
+
+A relative path to your OpenAPI spec file within the repository. Note that you might need an additional step in your GitHub workflow to generate this file (see [FastAPI example](https://fastapi.tiangolo.com/how-to/extending-openapi/#generate-the-openapi-schema)).
+
+## Next Steps
+
+Please follow the [integrations guide](https://heyapi.vercel.app/openapi-ts/integrations.html) on our website for the next steps.
