+### Systemd Service Generation
+
+The role can automatically generate systemd service files for containers and pods. This functionality helps in managing container lifecycle through systemd.
+
+* `podman_generate_systemd`: Enable systemd service generation (default: `true`)
+* `podman_systemd_dir`: Directory for generated service files (default: `/etc/systemd/system`)
+
+**Global Systemd Options** (`podman_systemd_options`):
+
+```yaml
+podman_systemd_options:
+  new: true              # Generate new service files
+  force: true           # Overwrite existing files
+  restart_policy: unless-stopped  # Default restart policy
+  time: 120             # Stop timeout in seconds
+  no_header: false      # Include header in service files
+  wants: []             # Systemd unit Wants
+  after: []             # Systemd unit After
+  requires: []          # Systemd unit Requires
+  container_prefix: ""  # Prefix for container service names
+  pod_prefix: ""        # Prefix for pod service names
+  restart_sec: 30       # Restart delay in seconds
+```
+
+**Per-Container/Pod Configuration:**
+
+You can override global systemd options for individual containers or pods:
+
+```yaml
+podman_containers:
+  - name: webapp
+    image: nginx:latest
+    systemd:
+      restart_policy: always
+      after: ["network.target"]
+      wants: ["network-online.target"]
+      restart_sec: 10
+
+podman_pods:
+  - name: database
+    systemd:
+      restart_policy: on-failure
+      requires: ["network.target"]
+      time: 180
+```
+
+When `systemd` is defined for a container or pod, the role will:
+1. Generate a systemd service file
+2. Place it in the specified directory
+3. Reload systemd daemon
+4. (Optional) Enable and start the service
+
+**Note:** Container/pod-specific options take precedence over global options defined in `podman_systemd_options`.
+
+### Resource Pruning
+
+The role can automatically clean up unused Podman resources to free up disk space and maintain system hygiene.
+
+* `podman_prune_enabled`: Enable automatic pruning of unused resources (default: `true`)
+* `podman_prune_options`: Configuration for what should be pruned
+
+```yaml
+podman_prune_options:
+  container: true    # Remove stopped containers
+  image: true        # Remove unused images
+  network: true      # Remove unused networks
+  system: true       # Prune all unused data
+  system_all: true   # Prune all unused data including build cache
+  volume: true       # Remove unused volumes
+```
+
+You can selectively disable certain types of pruning by setting their values to `false`:
+
+```yaml
+podman_prune_options:
+  container: true    # Still remove containers
+  image: false      # Keep all images
+  network: true     # Remove unused networks
+  system: false     # Keep system data
+  system_all: false # Keep build cache
+  volume: false     # Keep all volumes
+```
