Git is a version control system that allows developers to track changes made to their code and collaborate with others on a project. Git has become the industry standard for version control and is widely used in open source projects. In this blog post, we will explore Git basics and how to contribute to open source code using Git.

Git Basics
----------------

Before we dive into contributing to open source code, let's cover some basic Git concepts.

1. Git Repository: A Git repository is a folder that contains the project's source code, as well as metadata about the project's history and changes. A repository can be hosted on a local machine or on a remote server such as GitHub.

2. Commit: A commit is a snapshot of the repository at a specific point in time. Each commit includes a message that describes the changes made to the code.

3. Branch: A branch is a separate line of development in a repository. Branches are useful for testing new features or making changes without affecting the main codebase.

4. Merge: Merging combines two or more branches into a single branch.

5. Pull Request: A pull request is a proposed change to the codebase. Pull requests are used to submit code changes for review and approval by project maintainers.

Contributing to Open Source Code with Git
--------------------------------------------------

Now that we have covered the basic Git concepts, let's explore how to contribute to open source code using Git. We will use the **Apache AGE** repository as an example.

Step 1: Fork the Repository

The first step to contributing to open source code is to fork the repository. Forking creates a copy of the repository on your GitHub account. You can fork the Apache AGE repository by clicking on the "Fork" button on the repository's GitHub page.

Step 2: Clone the Repository

Next, you will need to clone the repository to your local machine. Cloning creates a local copy of the repository on your computer. You can clone the Apache AGE repository by running the following command in your terminal:

```
git clone https://github.com/YOUR_USERNAME/age.git
```

Replace YOUR_USERNAME with your GitHub username.

Step 3: Create a Branch

Before you start making changes to the code, it's a good idea to create a new branch. This allows you to make changes without affecting the main codebase. You can create a new branch by running the following command:

```
git checkout -b feature/new-feature
```

Replace "new-feature" with a descriptive name for your branch.

Step 4: Make Changes

Now you can start making changes to the code. You can use your favorite text editor to edit the files in the repository. Once you have made your changes, you can stage them for commit by running the following command:

```
git add .
```

This stages all changes made to the repository.

Step 5: Commit Changes

After staging your changes, you can commit them by running the following command:

```
git commit -m "Added new feature"
```

Replace "Added new feature" with a descriptive message that describes the changes made in the commit.

Step 6: Push Changes to GitHub

Now that you have committed your changes, you can push them to your fork on GitHub by running the following command:

```
git push origin feature/new-feature
```

This pushes your changes to the "feature/new-feature" branch on your fork of the Apache AGE repository.

Step 7: Create a Pull Request

The final step is to create a pull request. A pull request allows you to submit your changes for review and approval by the project maintainers. You can create a pull request by clicking on the "New pull request" button on the Apache AGE repository page on GitHub.

Conclusion
------------------

In conclusion, Git is a powerful tool for version control and collaboration. By following the steps outlined in this blog post, you should now have a basic understanding of Git and how to contribute to open source projects on GitHub. Remember to always create a fork, clone the repository, create a branch, make your changes, commit and push your changes to your forked repository, and finally create a pull request to contribute to the original repository. Happy coding and collaborating!
