+## Overview
+
+---
+
+This unit introduces Incident Response, a critical discipline in cybersecurity and systems administration focused on identifying,
+containing, eradicating, recovering from, and learning from system incidents. This unit also demonstrates the crucial need for
+policies and procedures in the likely event an incident occurs which facilitate successful remedies for administrators during
+stressful events.
+
+By the end of this unit, you'll understand the key phases and practices for developing and executing an effective incident
+response plan within enterprise environments to minimize the impact of system incidences.
+
+## Learning Objectives
+
+---
+
+**By the end of this unit, you should be able to:**
+
+- Define the stages of the incident response lifecycle.
+- Understand the roles and responsibilities within an incident response team.
+- Outline steps for initial incident detection and triage.
+- Describe methods for system recovery and post-incident analysis.
+
+## Relevance & Context
+
+---
+
+Incident response is paramount as it directly impacts an organization's ability to minimize the damage and financial costs associated
+with events like misconfigurations, bugs, security breaches or vulnerabilities, and more by enabling rapid action.
+
+An effective incident response plan also ensures business continuity, allowing systems and data to be restored efficiently and maintaining
+critical operations. Furthermore, robust incident response demonstrates adherence to regulatory compliance and builds trust with customers and stakeholders.
+
+## Prerequisites
+
+---
+
+**Before beginning this unit, ensure you understand:**
+
+- Basic networking concepts (TCP/IP, common protocols).
+- Fundamental operating system concepts (Linux/Windows file systems, processes, logging).
+- How to troubleshoot `systemctl` and systemd, `fstab`, `mount`, and Logical Volume Manager (LVM) tools.
+- Linux disk, partition, and mount configurations.
+- `dnf` and how to update system packages.
