How to enable the ELRepo repository

Introduction

ElRepo is an RPM repository that provides packages for Enterprise Linux operating systems. It supports Red Hat Enterprise Linux (RHEL) and its derivatives (such as CentOS and AlmaLinux).

The ELRepo Project focuses on hardware-related packages to enhance your experience with Enterprise Linux.
