Git

Git is a version control system, created by the owner of Linux. This control system allows the user to register new updates made over a code, storing this information.

GitHub

GitHub is an online platform where you create and store repositories to host projects and collaborate on open-source projects, working together with others.

GitHub is also a social network for developers, in addition to being a tool for teamwork.

A more detailed walkthrough I did on how to upload code to GitHub:

Step by step on how to use Git code

Important Concepts

• Repository: Local or remote environments that allow you to store your codes.
• Branch: It is a version (a branch) of your project. A repository can contain multiple branches.

Branches outside the main “Main” line are basically copies, which do not affect the main versioning of the project.

• Pull Request: It is linked to the fact that it sends a request to the other developers to perform a merge of the code in the main branch.
• Merge: To merge changes from working branches to main branch
