 ## Details
 
-These guides provide step-by-step procedures for controlling multiple terminal windows in the same persistent session.
+As a default, when your SSH connection terminates, any remote terminal sessions started by that connection also terminate. You can avoid that issue and reuse those sessions for yourself and others by using the tmux terminal multiplexer. You can also manage more complex tasks from a single SSH connection, as a terminal multiplexer can provide browser-style tabs for each task and even divide up your screen with multiple terminal sessions called panes.
 
-By default, terminating your SSH connection also terminates any remote terminal sessions started by that connection. If you use a terminal multiplexer, you can preserve those sessions for yourself and others to reuse. You can also manage more complex tasks from a single SSH connection, as a terminal multiplexer can provide browser-style tabs for each task, and even divide up your screen with multiple terminal sessions called "panes".

-In previous versions of Oracle Linux, you might have encountered a similar tool called `screen`, but in this tutorial you will explore `tmux`. This tutorial is targeted at users of Oracle Linux 8 or later.
+In previous versions of Oracle Linux, you might have encountered a similar tool called `screen`. This tool has been around for years and is still available in the Oracle developer EPEL repository. However, we'll focus on and explore `tmux,` which Oracle ships in the base repository.
 
 ### Objectives
 
-Upon completion of this Lab you will be able to:
+In this tutorial, you'll learn how to:
+
+   - Connect and disconnect from a persistent tmux session
+   - Display, hide, and switch between multiple terminals in the same tmux session
+   - Manage several persistent tmux sessions
 
-- Connect and disconnect from a persistent tmux session
-- Display, hide, and switch between multiple terminals in the same tmux session
-- Manage several persistent tmux sessions
+### Prerequisites
 
-### What do you need?
+- Minimum of a single Oracle Linux system
 
-- Any system with Oracle Linux 8
+- Each system should have Oracle Linux installed and configured with:
+    - A non-root user account with sudo access
+    - Access to the Internet

+## Details
+
+This video introduces you to DTrace, a microscope into the Operating System. DTrace is a tracing tool. It traces activities in both userland and the kernel. Learn the history of DTrace, how to install and run DTrace, understand terminology and concepts, and see an example of using DTrace.
