+### Container Management
+The CLI includes tools for managing Docker containers:
+
+```bash
+# List running containers
+arm-cli container list
+
+# Attach to a container interactively (sources ROS and interactive entrypoints)
+arm-cli container attach
+
+# Restart a container
+arm-cli container restart
+
+# Stop a container
+arm-cli container stop
+```
+
+For more details on container compliance, see [arm_cli/container/readme.md](arm_cli/container/readme.md).
 ## Development
 
 To contribute to this tool, first checkout the code. Then create a new virtual environment. From the root of the repo:

+Container Compliance for arm-cli
+
+While not strictly necessary, to work with arm-cli's interactive attach:
+
+## Entrypoint Scripts
+
+arm-cli attach will automatically source the following scripts if they exist:
+
+1. `/ros_entrypoint.sh` - Standard ROS entrypoint script
+2. `/interactive_entrypoint.sh` - Custom interactive entrypoint script
+
+### ROS Entrypoint Script
+
+Most ROS containers already include `/ros_entrypoint.sh`. This script typically:
+- Sets up ROS environment variables
+- Sources ROS setup files
+- Configures the ROS workspace
+
+### Interactive Entrypoint Script
+
+Add /interactive_entrypoint.sh in your image:
+
+```
+#!/bin/bash
+[ -f /opt/ros/$ROS_DISTRO/setup.bash ] && source /opt/ros/$ROS_DISTRO/setup.bash
+[ -f /ros2_ws/install/setup.bash ] && source /ros2_ws/install/setup.bash
+exec "$@"
+```
+
+Dockerfile:
+```
+COPY interactive_entrypoint.sh /interactive_entrypoint.sh
+ENTRYPOINT ["/interactive_entrypoint.sh"]
+```
+
+Behavior:
+arm-cli attach <container> sources both scripts in order if present:
+1. First sources `/ros_entrypoint.sh` (if it exists)
+2. Then sources `/interactive_entrypoint.sh` (if it exists)
+3. Falls back to plain bash if neither exists
