 ### Configuration
 
+#### Option A — Use the CLI (recommended)
+
+Generate `devcontainer.json` and `devcontainer.env.json` with a single command:

+```bash
+# From the repository root
+python -m cli.scaffold_devcontainer \
+  --languages python,java,go \
+  --cicd-tools docker,terraform,kubectl,helm \
+  --kubernetes-tools k9s,kustomize,argocd_cli,flux \
+  --devops-tools prometheus,grafana
+
+# Or via the unified CLI
+python -m cli.devopsos scaffold devcontainer
+```
+
+Run `python -m cli.scaffold_devcontainer --help` to see all available options including version overrides (`--python-version`, `--go-version`, etc.).

+Generate a dev container configuration from the CLI instead of editing JSON by hand:
+
+```bash
+# Generate devcontainer.json and devcontainer.env.json for a Python + Go project
+python -m cli.scaffold_devcontainer \
+  --languages python,go \

+You can also customize `.devcontainer/devcontainer.env.json` directly to enable or disable any language or tool, then reopen in VS Code.
