-## Docker not available inside the sandbox on Windows
-
-On Windows, sandboxes use non-docker template variants by default, so `docker`
-commands aren't available inside the sandbox. To use Docker inside a sandbox on
-Windows, specify a `-docker` template:
-
-```console
-$ sbx run --template docker.io/docker/sandbox-templates:claude-code-docker claude
