How to Install Homebrew on macOS

Introduction 

Homebrew is a package manager inspired by GBU/Linux OS’es, such as Aptitude or RPM, which allow you to install required libraries with the use of a few commands. Installing applications such as MySQL or PHP with Homebrew takes seconds while installing them manually could take at least 10 minutes and cause confusion if you don’t have much experience with the Mac Terminal. 

Requirements 

Homebrew relies upon Xcode. Make sure you have Xcode installed, and if not, you can find Xcode in the Apple AppStore

You will be required to have some fluency with the Mac Terminal App which is situated in the Utilities Folder under the Applications Folder.  

Installation Process  

Installing Homebrew is straightforward; you’re only required to paste a single line of code in to your Terminal in order to install it.   

1. Open your Terminal App

When necessary, you can update Homebrew by simply using the following command in the Terminal App:
