Basics of Git. Basic Commands & how to use it?

Git is a distributed version control system that is used to track changes to files and manage projects. It allows developers to collaborate on projects by keeping a record of all the changes made to the project's codebase. Here are some basic concepts and steps for using Git:

• Repository: A repository is a collection of files and the history of changes made to those files. A Git repository contains all the necessary files for a project, as well as a record of every change made to those files.
• Commit: A commit is a snapshot of the changes made to the files in a repository. When you commit changes, you are creating a new version of the project's codebase with a message that describes the changes you made.
• Branch: A branch is a separate version of a repository that allows you to make changes to the codebase without affecting the main codebase. This allows multiple developers to work on different features or bug fixes simultaneously without interfering with each other.
• Merge: When you are finished making changes on a branch, you can merge those changes back into the main codebase by creating a pull request and having it reviewed and approved by other members of the team.

To use Git, you will need to install it on your computer and set up a repository for your project. Here are the basic steps for using Git:

1. Initialize a new Git repository by running the "git init" command in the terminal.
2. Add files to the repository by running the "git add" command and specifying the file names or paths.
3. Commit the changes you have made to the repository by running the "git commit" command and including a message that describes the changes.
4. Create a new branch by running the "git branch" command and specifying the name of the branch.
5. Switch to the new branch by running the "git checkout" command and specifying the name of the branch.
6. Make changes to the codebase on the new branch.
7. Commit the changes you have made to the new branch.
8. When you are ready to merge the changes back into the main codebase, create a pull request on GitHub or a similar platform and have it reviewed and approved by other members of the team.
9. Merge the changes into the main codebase by running the "git merge" command and specifying the name of the branch.

These are the basic steps for using Git, but there are many other commands and features available that allow you to manage and collaborate on projects more effectively.
