+## Usage via `nix run`
+
+# Create container defined by ./flake.nix
+nix run . -- create
+# The arguments after `--` are passed to the `extra-container` binary in PATH,
+# while the flake is used for the container definitions.
+
+# Destroy container
+nix run . -- destroy
+
+# Start an interactive shell in the container
+nix run . -- shell
+nix run . # equivalent, because `shell` is used as the default command
+
+# Run a single command in the container.
+# The container is destroyed afterwards.
+nix run . -- --run c hostname
+nix run . -- shell --run c hostname # equivalent
+nix run . -- --run bash -c 'curl --http0.9 $ip:50'
+
+
+## Usage via `nix build`
+# 1. Build container
+nix build . --out-link /tmp/container
+# 2. Run container
+extra-container shell /tmp/container
+
+
+## Inspect container configs
+nix eval . --apply 'sys: sys.containers.demo.config.networking.hostName'
