 ## Details
 
-The following tutorial shows you how to configure an Oracle Linux system with disk encryption that is dependent on a network based key service.
+This tutorial demonstrates how to configure an Oracle Linux system with Linux Unified Key Setup (LUKS) disk encryption that is dependent on a network-based key service consisting of [Tang](https://github.com/latchset/tang) and [Clevis](https://github.com/latchset/clevis). You will create an encrypted XFS file system that is automatically unlocked at boot when on the same network as your key server.
 
 ### Objectives

+In this tutorial, you'll learn how to:
+
+  - Set up LUKS using [cryptsetup](https://gitlab.com/cryptsetup/cryptsetup/-/wikis/home), which provides the tooling for disk-based encryption and includes support for LUKS.
+  - Configure Tang as a network service that provides cryptographic services over HTTP.
+  - Use Clevis for the network encryption framework. Clevis can use keys provided by Tang as a passphrase to unlock LUKS volumes.
 
-- Create an encrypted XFS file system that is automatically unlocked at boot when on the same network as your key server 
-- This tutorial is targeted at users of Oracle Linux 8 or later.
 
 ### Prerequisites
 
-The tutorial uses the following system:
+- Minimum of two Oracle Linux systems
+
+- Each system should have Oracle Linux installed and configured with:
+    - A non-root user account with sudo access
+    - Access to the Internet
+    - A disk or block device attached to the system to use for encrypted storage
 
-- Two systems with Oracle Linux 8 installed.
-- A disk or block device attached to one system to use for encrypted storage
