UNDERSTANDING THE GIT WORKFLOW

Git is a tool for managing changes to code in software projects. It records the history of every modification made to a project's files. Git allows developers to collaborate together on the same codebase while tracking each individual change.

To begin using Git, first create a new repository by initializing Git in the project directory: `git init`. This creates a hidden `.git` folder where Git stores all the necessary tracking information.

After initializing the repository, check its status with `git status`. This command shows which files are currently tracked and which are untracked. Untracked files are those that Git has not been told to monitor, while tracked files are under Git's version control.

To add files to the staging area, use `git add` followed by the file name or a wildcard to include all files. For example, `git add .` stages all new, modified, and deleted files in the current directory and its subdirectories.

Once files are staged, commit the changes with `git commit -m "description"`. The `-m` flag allows you to provide a short message explaining the changes made in this commit. Commit messages should be clear and informative to help others understand the purpose of the changes.

When you're ready to share your changes with others, push them to a remote repository like GitHub using `git push`. This sends your commits from your local repository to the remote repository, making them visible to the development team.

Git does not store a separate copy of every file in each commit. Instead, it efficiently keeps track of changes made in each commit, saving storage space while still allowing for easy comparison between different versions of the code. The key to using Git effectively is to commit frequently and write meaningful commit messages that accurately describe the changes made in each commit.
