# Setup

To follow this tutorial, you will need:

1. **An SSH client**: Most Linux and macOS systems come with SSH pre-installed. Windows 10 and later include OpenSSH by default. To check if SSH is installed, open a terminal and type:
   ```bash
   ssh -V
   ```

2. **Access to a remote server**: You'll need credentials (username and hostname/IP address) for a server you can connect to. This might be:
   - A computing cluster at your institution
   - A cloud server
   - A virtual machine

3. **A text editor**: For editing the SSH configuration file. Any plain text editor will work (vim, nano, emacs, notepad++, VS Code, etc.)

If you don't have access to a server yet, please contact your supervisor or system administrator to obtain the necessary credentials and permissions.
