+# Multi-runner scale-set example
+
+This example demonstrates the experimental multi-runner v2 interface. Shared
+defaults are configured with `experimental_global_config*` variables, while
+each runner lane uses `experimental_multi_runner_config` for its matcher,
+runner lifecycle, and compute-provider settings.
+
+The example creates four lanes from one deployment:
+
+- Linux ARM64 Amazon Linux runners.
+- Ephemeral Linux x64 Amazon Linux runners with job retry enabled.
+- Linux x64 runners managed by a GitHub Actions scale set.
+- Windows x64 Server Core 2022 runners.
+
+The v2 interface keeps provider-owned settings inside the selected provider
+configuration. For example, VPC and subnet settings are under
+`experimental_global_config_compute_provider.aws.ec2`, while the per-lane
+instance types and AMI filter are under each lane's compute provider block.
+
+The scale-set lane uses `orchestration_provider.scale_set`. Its controller
+network is configured under the global scale-set block and its GitHub
+installation ID is read from the SSM parameter described by `var.scale_set`.
+
+Configure the GitHub App variables before applying:
+
+```bash
+terraform init
+terraform apply \
+  -var='github_app={id="123456",key_base64="..."}' \
+  -var='scale_set={config_url="https://github.com/example" installation_id_ssm={name="/github/scale-set/installation-id",arn="arn:aws:ssm:eu-west-1:123456789012:parameter/github/scale-set/installation-id"} name="linux-scale-set" id=123}'
+```
+
+The `github_app` value is sensitive and should be supplied through a secure
+variable source in real deployments rather than committed to configuration.
+The scale-set installation ID must already exist in the referenced SSM
+parameter and the GitHub App must be installed for the configured URL.
