Install Ruby on Rails 7 on Linuxmint

If you would like to try Ruby on Rails 7 with Ruby 3 on Linuxmint 20.03, I am quickly going to demonstrate how to install Ruby, Node, NPM, Yarn, git, build essentials, Ruby on Rails 7 and all other required packages and also will create the demo Rails app and run the Rails server and pull up the rails app in my preferred web browser. There a screencast video of the process that you can find at bottom of the page.
