What is GitHub and how to start using it?

GitHub is an essential tool in the world of programming and software development, although its usefulness is not limited to software engineers. This platform has gained immense popularity for its ability to facilitate project collaboration, version control and efficient code and file management. In this blog, we explain what GitHub is, why it's so popular and how you can get started using it.

What is GitHub?

GitHub is a cloud-based platform that allows developers to manage projects using a version control system called Git. It facilitates collaboration between multiple people, even if they are working remotely, by allowing you to keep a detailed record of changes made to a project's files. This is crucial when several developers are working simultaneously, as they can make changes without interfering with each other's work.

What is version control?

Version control is a system that allows you to track changes made to files over time. It is especially useful for developers, who constantly modify the source code of a project. If a mistake is made, you can revert to a previous version of the file without losing the previous changes. Version control allows multiple collaborators to work on different parts of a project without affecting the code base until changes are reviewed and approved.

What is Git?

Git is a distributed version control system that allows developers to work on different branches of the project independently. This means that each contributor has a local copy of the project, where they can make changes without affecting the original code until those changes are approved. Git allows the creation of “branches” where new features can be developed without risking the stability of the main version.

Git is very efficient because it distributes responsibility for version control among all team members, and is the foundation that makes GitHub work.

Why is GitHub so popular?

GitHub is not only a code storage platform, but also a tool that facilitates collaboration and project tracking. One of the reasons it is so popular is its ease of use and intuitive graphical interface that allows users to take advantage of Git's functionality without having to use the command line.

Other reasons for its popularity:

• Team collaboration: GitHub allows multiple developers to work simultaneously on a project, keeping all change history and making code review easier.
• Open source: GitHub is home to millions of open source projects, allowing anyone to learn, contribute and use the code of others.
• Integration with development tools: GitHub easily integrates with other development tools, facilitating workflow for software teams.
• Communities and networking: As a global platform, GitHub connects developers around the world, providing opportunities for learning and collaboration on projects.

How to start using GitHub?

Getting started with GitHub is a simple process, even if you have no previous experience with the platform or version control systems. Here are the basic steps to get you started:

1.Creating a Repository

The first step is to create a repository. A repository is the place where you will store all the files related to your project. It can include code, documentation, images and any other necessary files.

Steps to create a repository

• Log in to GitHub and click the “New repository” button to create a new repository.

• Choose a name for your repository and define whether it will be public (visible to everyone) or private.
• Check the “Add a README file” option to include a description of the project.
• Click on “Create repository” to finish.

2. Creating branches

Branches allow you to work on different versions of a project without affecting the main version (called “main” or “master”). You can use a branch to develop new features or fix bugs, and when they are ready, merge them with the main branch.

Steps to create a branch:

• Go to the repository you created.
• Click on the drop-down menu that shows “main” and type in the name of the new branch.
• Click “Create branch” to create a new version of the project.

3. Making commits

A commit is the equivalent of saving changes. Every time you make changes to your code or files, you must commit to record those changes in the branch you are working on.

How to make a commit:

• Select the branch you are working on.

• Make the changes to the files you need. In our case, we are going to upload a new file to the project.
• Write a brief description of the change and click “Commit changes”.

4. Create pull requests

A pull request is a request for your changes to be reviewed and, if approved, integrated into the main branch of the project. This step is fundamental in team collaboration, as it allows other members to review your code before merging it.

Steps to create a pull request:

• Click on “Pull requests” inside the repository, select “New pull request” and choose the branch you worked on.
• Review the changes and click “Create pull request”, adding a brief description of the work done.

Once the pull request is approved by your teammates, they will be able to merge the changes with the main branch.

How to use GitHub from the command line?

In addition to the graphical interface, GitHub can be managed from the command line using Git. This option is preferred by many developers, as it offers more direct control over their projects.

If you are interested in learning how to use Git from the command line, you can refer to our Git Basic Commands Guide, where you will find a list of the most useful commands and how to use them to manage your repositories on GitHub.
