Use VIM Editor with confidence for All need

Hi Guys!!!
Today I am going to discus "How to use Vi /VIM Editor with confidence"
Getting Vim Installed
If you’re on Linux, you likely already have Vim installed. If not, run one of these commands:

sudo apt install vim vim-gnome

sudo yum install vim gvim

Introduction
Vim is just a text editor. 

But if you have ever seen an expert using vim, you come to know that : 

• It is shockingly powerful, efficient, and fast.
• At a high level, vim is a tool that allows you to more clearly better describe what you are trying to do when editing text. 
• Once you become fluent in vim’s language, you will be able to communicate with your computer at a much greater speed.
