 `gitx` is a Terminal User Interface (TUI) built with Go to help you learn and interact with Git. It provides a visual way to handle common Git commands, making it easier for both beginners and experienced users to manage their repositories without leaving the terminal.
 
 Inspired by `lazygit`, `gitx` aims to provide a guided and educational experience.
