First of all, let's understand what Homebrew is and what things he adds to our daily.
What is Homebrew?
Homebrew installs the stuff you need that Apple (or your Linux system) didn’t.
Whit that we can easily install any package we are missing on our machine just using the terminal.
Let's go further and install it.
To install we only need to open
terminal and past this line
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
With the Homebrew installed to add new "things" you only need to run the command like this:
brew install package-name
