+# `buildx inspect [NAME]`
+
+## Description
+
+Shows information about the current or specified builder.
+
+Example:
+
+```console
+$ docker buildx inspect elated_tesla
+
+Name:   elated_tesla
+Driver: docker-container
+
+Nodes:
+Name:      elated_tesla0
+Endpoint:  unix:///var/run/docker.sock
+Status:    running
+Platforms: linux/amd64
+
+Name:      elated_tesla1
+Endpoint:  ssh://ubuntu@1.2.3.4
+Status:    running
+Platforms: linux/arm64, linux/arm/v7, linux/arm/v6
+```
+
+### `--bootstrap`
+
+Ensures that the builder is running before inspecting it. If the driver is
+`docker-container`, then `--bootstrap` starts the buildkit container and waits
+until it is operational. Bootstrapping is automatically done during build, it is
+thus not necessary. The same BuildKit container is used during the lifetime of
+the associated builder node (as displayed in `buildx ls`).
