 ## Notes
 
-### BuildKit container logs
+### `nodes` output
 
-To display BuildKit container logs (when `docker-container` driver is used) you have to [enable step debug logging](https://docs.github.com/en/actions/managing-workflow-runs/enabling-debug-logging#enabling-step-debug-logging)
+```json
-or you can also enable debugging in the [setup-buildx action step](https://github.com/docker/setup-buildx-action):
+[
-
+  {
-```yaml
+     "name": "builder-3820d274-502c-4498-ae24-d4c32b3023d90",
-  -
+     "endpoint": "unix:///var/run/docker.sock",
-    name: Set up Docker Buildx
+     "driver-opts": [
-    uses: docker/setup-buildx-action@v1
+       "network=host",
-    with:
+       "image=moby/buildkit:master"
-      buildkitd-flags: --debug
+     ],
+    "status": "running",

+    "platforms": "linux/amd64,linux/amd64/v2,linux/amd64/v3,linux/amd64/v4,linux/386"
+  }
+]
 ```
 
-Logs will be available at the end of a job:
+| Name              | Type   | Description                |
+|-------------------|--------|----------------------------|
+| `name`            | String | Node name                  |

+| `driver-opts`     | List   | Options for the driver     |
+| `status`          | String | Node status                |
+| `buildkitd-flags` | String | Flags for buildkitd daemon |
+| `buildkit`        | String | BuildKit version           |
+| `platforms`       | String | Platforms available        |
