-## Introduction
+# Connecting to the HPC Cluster
 
 There are several ways to interact with the Greene HPC cluster. Similar to other Linux clusters, the most common method of connection is via a Command Line Interface (CLI). A CLI is a program that allows you to create and delete files, run programs, and navigate through directories and files via a typed prompt. On Mac, the built-in CLI application is called Terminal. While Windows 11 machines support a Linux Subsystem, which allows for similar functionality, a popular tool used to connect to a Linux server is a free application called [PuTTY][putty link].
