+# aws-configure
+
+Authenticate with AWS via OIDC and export credentials to the environment.
+
+## Inputs
+
+| Input | Required | Default | Description |
+|-------|----------|---------|-------------|
+| `role-arn` | Yes | | Full IAM role ARN |
+| `aws-profile` | No | `default` | Profile name written to `~/.aws/config` |
+| `region` | No | `eu-central-1` | AWS region |
+
+## Usage
+
+```yaml
+- uses: schmalz/shared-actions/.github/actions/aws-configure@v1
+  with:
+    role-arn: arn:aws:iam::123456789012:role/my-role
+```
+
+## Notes
+
+- Requires `enable-openid-connect: true` on the Forgejo runner job.
+- Credentials are exported via `$FORGEJO_ENV` so subsequent steps can use them.
+- When `aws-profile` is not `default`, a named AWS CLI profile is also configured.
