Master GitHub: A Beginner’s Guide to Version Control and Code Management

1 Introduction

First, what are GitHub and Git , and why should we use these tools?

When multiple people work on different parts of a document or code, countless versioned files (e.g., "Part1_1", "Part1_2", "Modify1", etc.) can quickly become chaotic, making it hard to revert to a previous state. GitHub solves this problem by providing a repository that tracks each file’s versions, users, timestamps, and changes, allowing easy download and rollback.

GitHub is a web‑based platform that hosts repositories; Git is the command‑line software that interacts with those repositories. Together they enable uploading local code files to the GitHub website.

Git is not the only tool for this purpose—alternatives such as the Chinese platform Gitee also exist and may offer better speed and stability.

2 Usage

There are two common ways to use GitHub: (1) create a repository on the GitHub website first, then sync it to your local machine; or (2) work locally first and then push to GitHub. The first method is considered more convenient.

2.1 GitHub Configuration

Log in to https://github.com/ , register an account, and click the “New” button to create a new repository. Give the repository a name and a brief description.

After creation, the repository contains default README and License files.

In the repository’s “Code” tab, copy the SSH URL for later use.

2.2 Git Configuration

Download and install the Git software. Then open Git Bash in a suitable folder and run the following command to clone a repository (replace the URL with your own SSH URL):

git clone [email protected]:Chutj/Crop_Yield_Prediction_with_Machine_Learning.git

After cloning, the local folder will contain the README and License files.

2.3 Uploading Code to GitHub

Write or edit your code locally, then use Git Bash to add, commit, and push the changes.

git add CropYield_DL_Old.py

Commit the changes with a descriptive message:

git commit -m"Modify This File"

Finally, push the commit to GitHub:

git push

This completes a simple GitHub and Git workflow. The tutorial is intentionally basic and does not cover advanced Git features such as version rollback; readers are encouraged to explore more detailed resources.
