To make a new rails app, create a folder to contain the source code, then navigate into it.

mkdir workspace
cd workspace

Next, run the rails new command to create your application.

rails new hello-world --skip-yarn

Run rails server locally

Finally, navigate to the hello-world folder, and run rails server to launch the rails app in a browser.
