In this section, we will guide you through the process of installing Prolog on your system. Prolog is available for various operating systems, including Windows, macOS, and Linux. We will cover the installation steps for each of these platforms.

1. Download SWI-Prolog:

   • Visit the SWI-Prolog download page.
   • Click on the link for the Windows installer (usually a .exe file).

2. Run the Installer:

   • Locate the downloaded installer file and double-click it to run.
   • Follow the on-screen instructions to complete the installation. You can typically accept the default settings.

3. Verify the Installation:

   • Open the Command Prompt (you can search for "cmd" in the Start menu).
   • Type swipl and press Enter. You should see the SWI-Prolog prompt (?-), indicating that Prolog is installed correctly.

1. Install Homebrew (if not already installed):

   • Open the Terminal application.
   • Install Homebrew by running the following command:

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

2. Install SWI-Prolog:

   • Once Homebrew is installed, run the following command in the Terminal:

     brew install swi-prolog
     

3. Verify the Installation:

   • In the Terminal, type swipl and press Enter. You should see the SWI-Prolog prompt (?-), indicating that Prolog is installed correctly.

1. Using Package Manager:

   • Open the Terminal.

2. For Debian-based distributions (e.g., Ubuntu):

   • Run the following commands:

     sudo apt update
     sudo apt install swi-prolog
     

3. For Red Hat-based distributions (e.g., Fedora):

   • Run the following commands:

     sudo dnf install swi-prolog
     

4. Verify the Installation:

   • In the Terminal, type swipl and press Enter. You should see the SWI-Prolog prompt (?-), indicating that Prolog is installed correctly.

By following the steps outlined above, you should now have Prolog installed on your system. You can verify the installation by running the swipl command in your terminal or command prompt. In the next section, we will take our first steps in Prolog, where you will learn how to write and run your first Prolog program.
