+### Direct Host Connection
+
+SSHM supports direct connection to hosts via the command line, making it easy to integrate into your existing workflow:
+
+```bash
+# Connect directly to any configured host
+sshm production-server
+sshm db-staging
+sshm web-01
+
+# All direct connections are tracked in your history
+# Use the TUI to see your most recently connected hosts
+```
+
+**Features of Direct Connection:**
+- **Instant connection** - No TUI navigation required
+- **History tracking** - All connections are recorded with timestamps
+- **Error handling** - Clear messages if host doesn't exist or configuration issues
+- **Config file support** - Works with custom config files using `-c` flag
+
+### Backup Configuration
+
+SSHM automatically creates backups of your SSH configuration files before making any changes to ensure your configurations are safe.
+
+**Backup Location:**
+- **Unix/Linux/macOS**: `~/.config/sshm/backups/` (or `$XDG_CONFIG_HOME/sshm/backups/` if set)
+- **Windows**: `%APPDATA%\sshm\backups\` (fallback: `%USERPROFILE%\.config\sshm\backups\`)
+
+**Key Features:**
+- Automatic backup before any modification
+- One backup per file (overwrites previous backup)
+- Stored separately to avoid SSH Include conflicts
+- Easy manual recovery if needed
+
+**Additional Storage:**
+- **Connection History**: Stored in the same config directory for persistent tracking
+- **Port Forwarding History**: Saved configurations for quick reuse of common forwarding setups
+
+**Quick Recovery:**
+```bash
+# Unix/Linux/macOS
+cp ~/.config/sshm/backups/config.backup ~/.ssh/config
+
+# Windows
+copy "%APPDATA%\sshm\backups\config.backup" "%USERPROFILE%\.ssh\config"
+```
+
 ### Configuration File Options
 
 By default, SSHM uses the standard SSH configuration file at `~/.ssh/config`. You can specify a different configuration file using the `-c` flag:
@@ -253,8 +318,96 @@ sshm -c /path/to/custom/ssh_config
 # Use custom config file with commands

 sshm edit hostname -c /path/to/custom/ssh_config
+sshm move hostname -c /path/to/custom/ssh_config
 ```
 
+### Advanced Features
+
+#### Host Movement Between Config Files
+
+SSHM provides a powerful `move` command to relocate SSH hosts between different configuration files. **This feature requires SSH Include directives to be present in your SSH configuration.**
+
+```bash
+# Move a host to another config file (requires Include directives)
+sshm move my-server
+
+# Move with custom config file (requires Include directives)
+sshm move my-server -c /path/to/custom/ssh_config
+```
+
+**⚠️ Important Requirements:**
+- **SSH Include directives must be present** in your SSH config file (either `~/.ssh/config` or the file specified with `-c`)
+- The config file must contain `Include` statements referencing other SSH configuration files
+- Without Include directives, the move command will display an error message
+
+**Features:**
+- **Interactive file selector** - Choose destination config file from Include directives
+- **Include support** - Works seamlessly with SSH Include directives structure
+- **Atomic operations** - Safe host movement with automatic backups
+- **Validation** - Prevents conflicts and ensures configuration integrity
+- **Error handling** - Clear messages when Include files are needed but not found
+
+**Use Cases:**
+- Reorganize hosts from main config to specialized include files
+- Move development hosts to separate environment-specific configs
+- Consolidate configurations for better organization
+
+**Example Setup Required:**
+Your main SSH config file must contain Include directives like:
+```ssh
+# ~/.ssh/config
+Include ~/.ssh/config.d/*
+Include work-servers.conf
+Include projects/*.conf
+
+Host personal-server
+    HostName personal.example.com
+    User myuser
+```
+
+#### Real-time Connectivity Status
+
+SSHM features asynchronous SSH connectivity checking that provides visual indicators of host availability:
+
+**Status Indicators:**
+- 🟢 **Online** - SSH connection successful (shows response time)
+- 🟡 **Connecting** - Currently testing connectivity
+- 🔴 **Offline** - SSH connection failed or host unreachable
+- ⚫ **Unknown** - Status not yet determined
+
+**Features:**
+- **Non-blocking checks** - Status updates happen in the background
+- **Response time tracking** - See connection latency for online hosts
+- **Automatic refresh** - Status indicators update continuously
+- **Error details** - Detailed error information for failed connections
+
+#### Automatic Update Checking
+
+SSHM includes built-in version checking that notifies you of available updates:
+
+**Features:**
+- **Background checking** - Version check happens asynchronously
+- **Release notifications** - Clear indicators when updates are available
+- **Pre-release detection** - Identifies beta and development versions
+- **GitHub integration** - Direct links to release pages
+- **Non-intrusive** - Updates don't interrupt your workflow
+
+**Update notifications appear:**
+- In the main TUI interface as a subtle notification
+- In the `sshm --version` command output
+- Only when a newer stable version is available
+
+#### Port Forwarding History
+
+SSHM remembers your port forwarding configurations for easy reuse:
+
+**Features:**
+- **Automatic saving** - Successful forwarding setups are saved automatically
+- **Quick reuse** - Previously used configurations appear as suggestions
+- **Per-host history** - Forwarding history is tracked per SSH host
+- **All forward types** - Supports Local (-L), Remote (-R), and Dynamic (-D) forwarding history
+- **Persistent storage** - History survives application restarts

 SSHM works directly with your standard SSH configuration file (`~/.ssh/config`). It adds special comment tags for enhanced functionality while maintaining full compatibility with standard SSH tools.
 
+### SSH Include Support
+
+SSHM fully supports SSH Include directives, allowing you to organize your SSH configurations across multiple files. This is particularly useful for managing large numbers of hosts or organizing configurations by environment, project, or team.
+
+**Include Examples:**
+```ssh
+# Main ~/.ssh/config file
+Host personal-server
+    HostName personal.example.com
+    User myuser
+
+# Include work-related configurations
+Include work-servers.conf
+
+# Include all configurations from a directory
+Include projects/*
+
+# Include with relative paths
+Include ~/.ssh/configs/production.conf
+```
+
+**Organization Examples:**
+
+*work-servers.conf:*
+```ssh
+# Tags: work, production
+Host prod-web-01
+    HostName 10.0.1.10
+    User deploy
+    ProxyJump bastion.company.com
+
+# Tags: work, staging  
+Host staging-api
+    HostName staging-api.company.com
+    User developer
+```
+
+*projects/client-alpha.conf:*
+```ssh
+# Tags: client, development
+Host client-alpha-dev
+    HostName dev.client-alpha.com
+    User admin
+    Port 2222
+```
+
 **Example configuration:**
+Include ~/.ssh/conf.d/*
