Tekkub has developed a script to simplify the Git and GitHub setup process for new users, particularly those using Windows through msysgit, which often lacks default SSH-agent integration. The script automates the configuration of Git settings, the generation and uploading of SSH keys to GitHub, and encourages the use of strong passphrases and SSH-agent. It is designed to work immediately post-installation and accommodates Windows users by setting up SSH-agent to run automatically. While Mac and some Linux users benefit from built-in SSH-agent functionality, this script bridges the gap for Windows users. Tekkub invites feedback, suggestions, and pull requests to further enhance the script, and has also created a guide on the importance of using strong passphrases with SSH keys.
