+### Shell Completion
+
+SSHM supports shell completion for host names, making it easy to connect to hosts without typing full names:
+
+```bash
+sshm <TAB>           # Lists all available hosts
+sshm pro<TAB>        # Completes to hosts starting with "pro" (e.g., prod-server)
+```
+
+**Setup Instructions:**
+
+**Bash:**
+```bash
+# Enable for current session
+source <(sshm completion bash)
+
+# Enable permanently (add to ~/.bashrc)
+echo 'source <(sshm completion bash)' >> ~/.bashrc
+```
+
+**Zsh:**
+```bash
+# Enable for current session
+source <(sshm completion zsh)
+
+# Enable permanently (add to ~/.zshrc)
+echo 'source <(sshm completion zsh)' >> ~/.zshrc
+```
+
+**Fish:**
+```bash
+# Enable for current session
+sshm completion fish | source
+
+# Enable permanently
+sshm completion fish > ~/.config/fish/completions/sshm.fish
+```
+
+**PowerShell:**
+```powershell
+# Enable for current session
+sshm completion powershell | Out-String | Invoke-Expression
+
+# Enable permanently (add to your PowerShell profile)
+Add-Content $PROFILE 'sshm completion powershell | Out-String | Invoke-Expression'
+```

 ### Direct Host Connection
 
 SSHM supports direct connection to hosts via the command line, making it easy to integrate into your existing workflow:

 - **Config file support** - Works with custom config files using `-c` flag
 
+### Remote Command Execution
+
+Execute commands on remote hosts without opening an interactive shell:
+
+```bash
+# Execute a single command
+sshm prod-server uptime
+
+# Execute command with arguments
+sshm prod-server ls -la /var/log
+
+# Check disk usage
+sshm prod-server df -h
+
+# View logs (pipe to local commands)
+sshm prod-server 'cat /var/log/nginx/access.log' | grep 404
+
+# Force TTY allocation for interactive commands (sudo, vim, etc.)
+sshm -t prod-server sudo systemctl restart nginx
+```
+
+**Features:**
+- **Exit code propagation** - Remote command exit codes are passed through
+- **TTY support** - Use `-t` flag for commands requiring terminal interaction
+- **Pipe-friendly** - Output can be piped to local commands for processing
+- **History tracking** - Command executions are recorded in connection history
