How to Setup Git for Windows and macOS

Let’s Talk Git

Using Git for version control is a game-changer for developers. It offers numerous benefits that streamline your workflow and enhance collaboration. Here’s why Git should be a fundamental part of your development toolkit.

I use Git on all my projects because of the peace of mind it provides. In my tutorials on WordPress theme development with DevWP, Git has been part of what I teach for years.

Why Use Git for Version Control?

Tracking Changes

Git meticulously tracks every change made to your codebase, recording modifications, additions, and deletions. This comprehensive history allows you to understand your project’s evolution, review past changes, and pinpoint the source of issues.

Collaboration and Teamwork

Git is designed for collaboration. Multiple developers can work on different features simultaneously, with Git handling the seamless integration of their changes. It simplifies merging code, resolving conflicts, and maintaining a unified codebase.

Branching and Merging

Branches in Git are like alternate realities for your project. They allow you to work on new features or experiments without affecting the main codebase. Once your branch is ready, merge it back into the main branch to incorporate the changes. This approach encourages experimentation and efficient concurrent work management.

Reverting and Rollbacks

Made a mistake? No problem. Git allows you to revert changes or roll back to previous versions effortlessly. Whether you need to undo specific commits or reset branches, Git provides robust mechanisms to restore your code to a known good state.

Backup and Disaster Recovery

Git automatically creates redundant copies of your code across different machines or repositories. This redundancy acts as a backup, ensuring your code is safe even if your local copy is lost or corrupted. Git hosting platforms like GitHub or GitLab offer additional security and backup options.

Code Reviews and Collaboration

Git integrates seamlessly with code review tools and workflows. Create pull requests or merge requests to allow team members to review your code, suggest improvements, and catch errors before merging into the main branch. This process fosters collaboration, knowledge sharing, and code quality improvement.

Open Source Community

Git is the de facto standard for version control in the open-source community. Using Git makes it easier to contribute to open-source projects or share your work with others. Git hosting platforms provide mechanisms for forking repositories, submitting pull requests, and collaborating with developers globally.

Overall, Git’s versatility, scalability, and extensive tooling ecosystem make it an indispensable version control system for projects of any size, promoting collaboration, flexibility, and effective change management.

What are Branches?

Branches are the Multiverse.

Branches create alternate realities for your project. This powerful feature allows you to experiment and develop new features without impacting the main codebase. Once ready, you can merge your changes back into the main branch, maintaining a clean and stable project history.

How to Install Git on macOS

Using Homebrew

Homebrew Website

Homebrew is a package manager that simplifies the installation of software on macOS. It also installs the necessary command line development tools if Xcode isn’t already installed.

1. Install Homebrew: Open your terminal and run:

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

2. Install Git via Homebrew:

   brew install git
