The steps below assume that you're using MacOS. Ruby installation, Rails installation, and general commands and filepaths with be different for Windows. Please reference the video that I followed while studying for Rails/Ruby installation steps specific to Windows

• Ruby version >= v2.5.0
  • Ruby installation guide
  • Check your version with ruby -v
• sqlite3 (v3.32.3 worked for me)
  • Preinstalled on MacOS
  • Check your version with sqlite3 --version
• Node version >= v8.16.0
  • I used Homebrew to install node
  • npm is another option
  • Check your version with node -v
• Yarn (v1.22.10w worked for me)
  • Check your version with yarn -v

• Follow the prerequisite checks listed above OR use the Rails Guides "Getting Started" tutorial
• Run gem install rails and wait for the dependencies to be installed
  • Don't be worried if it looks like the process is stalled or stuck. There's a ton of tasks being performed in the background

• Pick the name you want to use for your project's directory (I'll use sample_app for the example)
• Open up your console of choice (VS Code's built-in, iTerm, Terminal, etc)
• Type mkdir sample_app and hit return (using your choice for your project's name instead)
• Type cd sample_app and hit return
• Type rails new . and hit return
  • This command will generate a rails template app and a bunch of files and install gem dependencies

• Pick the name you want to use for your project's directory (I'll use sample_app for the example)
• Create a new repository in Github and name it sample_app
• Copy the clone URL (should be https://github.com/<your_username>/sample_app.git)
• In your local console of choice, navigate to the parent directory under which you want to clone your new repository
• Type git clone https://github.com/<your_username>/sample_app.git replacing the URL with the URL to your new repository
• Type cd sample_app and hit return
• Type rails new . and hit return
  • This command will generate a rails template app and a bunch of files and install gem dependencies

• [Optional] Open up your sample_app project in your text editor of choice
• In your console of choice, run rails s
  • Your console output should indicate the URL where your Rails server is running. It should be localhost:3000
• In your web browser of choice, open up localhost:3000
• If everything is running successfully, then you should see the Rails success image
