+# HeroPods CLI
+
+The `hero pods` command provides a Docker/Podman-like CLI interface for managing HeroPods containers.
+
+## Installation
+
+Build the hero CLI:
+
+```bash
+v -o ~/hero cli/hero.v
+```
+
+## Commands
+
+### List Containers
+
+```bash
+hero pods ps
+```
+
+Lists all containers (running and stopped) with their status and PID.
+
+### List Images
+
+```bash
+hero pods images ls
+```
+
+Lists all available container images with size and creation time.
+
+### Create Container
+
+```bash
+hero pods create --name mycontainer alpine_3_20
+# or with Docker URL
+hero pods create --name mycontainer --docker-url docker.io/library/alpine:3.20
+```
+
+Creates a new container from an image.
+
+### Start Container
+
+```bash
+hero pods start mycontainer
+```
+
+Starts a stopped container.
+
+### Stop Container
+
+```bash
+hero pods stop mycontainer
+```
+
+Stops a running container.
+
+### Remove Container
+
+```bash
+hero pods rm mycontainer
+# Force remove running container
+hero pods rm --force mycontainer
+```
+
+Removes/deletes a container.
+
+### Execute Command
+
+```bash
+hero pods exec mycontainer ls -la
+hero pods exec mycontainer /bin/sh
+```
+
+Executes a command inside a running container.
+
+### Inspect Container
+
+```bash
+hero pods inspect mycontainer
+```
+
+Shows detailed information about a container including:
+
+- Status (running/stopped)
+- PID (if running)
+- Network namespace access commands
+- Crun management commands
+
+## Example Workflow
+
+```bash
+# List available images
+hero pods images ls
+
+# Create a container
+hero pods create --name test1 alpine_3_20
+
+# Start the container
+hero pods start test1
+
+# Execute commands in the container
+hero pods exec test1 ip addr show
+hero pods exec test1 ping -c 2 8.8.8.8
+
+# Inspect the container
+hero pods inspect test1
+
+# Stop the container
+hero pods stop test1
+
+# Remove the container
+hero pods rm test1
+```
+
+## Manual Container Access
+
+For manual testing and debugging, you can access containers directly using the information from `hero pods inspect`:
+
+```bash
+# Get container PID
+hero pods inspect mycontainer
+
+# Access container network namespace
+nsenter -t <PID> -n ip addr show
+
+# Get shell in container
+nsenter -t <PID> -n -m -p /bin/sh
+
+# Use crun directly
+crun --root /Users/user/.heropods/default/runtime exec mycontainer /bin/sh
+```
+
+## Notes
+
+- All containers are managed by the default HeroPods instance
+- Container networking uses bridge mode with automatic IP allocation
+- Images are pulled and extracted using Podman
+- The OCI runtime used is crun
