Homebrew is a package manager that simplifies software installation and management on macOS. If Homebrew is not installed, follow these steps:

1. 1. Launch the terminal app (located in /Applications/Utilities/).
   2. Enter the following instruction:

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"

1. Return and wait for the installation to finish.

Step 2: Install Ruby

After installing Homebrew, you may use it to install Ruby. Follow the instructions below:

1. 1. Launch your terminal program.
   2. Enter the following instruction:

brew install ruby

1. Return and wait for the installation to finish.

Step 3: Verify Ruby Installation

Follow these procedures to confirm that Ruby was installed properly:

1. 1. Launch your terminal program.
      Enter the following instruction:

ruby -v

1. Hit Enter. The installed version of Ruby should be displayed.

Step 4: Install a Text Editor

To write and modify Ruby code, you’ll need a text editor. Atom, Sublime Text, and Microsoft Studio Code are among the several solutions available. Install the option that best meets your requirements.

Step 5: Set Up Your Programming Environment

Installing Ruby and a text editor has prepared you to configure your development environment. Follow the instructions below:

1. 1. Create a folder just for your Ruby projects.
   2. Start a new file using your text editor.
   3. Enter Ruby code into the file.
   4. Save the file with the extension.rb in the new folder.
   5. Launch your terminal application and use the cd command to navigate to your new folder.
   6. Enter the command below to execute Ruby code:

ruby yourfile.rb

1. Simply press Return to execute Ruby code.

Tips for Working with Ruby

Now that Ruby and a local programming environment have been installed, here are some suggestions for working with Ruby:

• The irb command is used to launch the interactive Ruby shell. This is an excellent method for experimenting with Ruby code and evaluating new concepts.
• Use Ruby’s comprehensive documentation. In the terminal, you may obtain documentation for any Ruby method or class by entering ri methodname.
• Use a version manager such as rbenv or RVM to manage various Ruby versions on your system.
• Join the Ruby community by participating in meetups and online forums. Ruby developers have access to a vast amount of information and tools.
