Git Basics

Video tutorial that teaches Git basics in 15 minutes. The video introduces Git as a distributed version control system that allows users to track changes in an application, folder, or single file over time across different users and computers. The instructor then discusses their experience with Git and how it is helpful for large projects with multiple users.
The video then explains how to install Git and set up user configuration, including providing a username and email address. The instructor emphasizes that this information is only used to track who made what changes and is not used for logging in anywhere.
Next, the instructor briefly talks about GitHub and explains that it relies on Git, but they are separate tools. The video then focuses on repositories, which are containers for Git. To use Git on a project or file, the user needs to initialize a repository using the command “git init.”
The video then explains the “git status” command, which allows users to check the status of their repository. The instructor demonstrates this command by creating a new file called “index.html” and checking the status of the repository. The video explains that Git uses a two-step process for committing changes, where changes are first added to the staging area and then committed. The video shows how to add a file to the staging area using “git add” and then make a commit using “git commit -m,” followed by a message.
The instructor then demonstrates how to view commit history using “git log” and revert changes using “git checkout.” The video also covers branching and merging, which allow users to work on different versions of the code simultaneously and then merge them back together.
Finally, the video wraps up by reminding users to regularly commit changes, use descriptive commit messages, and practice good Git hygiene to avoid common mistakes. The instructor also encourages viewers to continue learning Git by exploring more advanced features and seeking additional resources.
