• Open a web browser.
• Go to http://localhost:8080 or http://your-server-ip:8080.
• Complete the setup by providing the initial admin password (found in /var/lib/jenkins/secrets/initialAdminPassword).

macOS:

• Install Homebrew (if not already installed):

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

• Install Jenkins:

                      brew install jenkins-lts
