To upload a folder or directory to GitHub, follow these steps [1][2][3][4]:
1. Create a GitHub Repository:
* Go to GitHub (https://github.com) and log in to your account.
* Click on the `+` icon in the top right corner and select `New repository`.
* Fill in the repository name, description, and other settings as needed.
* Choose the visibility (public or private) for your repository.
* Click the `Create repository` button.
2. Prepare Your Folder:
* Ensure that your folder contains the files you want to upload to GitHub.
* Include any necessary files like `README.md or .gitignore`.
3. Initialize Git in Your Folder:
* Open your terminal or command prompt.
* Navigate to the folder you want to upload using the cd command.
* Run the following commands to initialize a Git repository and make an initial commit.

        git init
        git add .
        git commit -m "Initial commit"

4. Link to Your GitHub Repository:
* On the GitHub repository page, copy the repository's URL (e.g., `https://github.com/yourusername/yourrepository.git)`.
* In your terminal, run the following command to add the remote repository:

        git remote add origin https://github.com/yourusername/yourrepository.git

5. Push Your Folder to GitHub: Run the following command to push your folder and its contents to GitHub. Replace `master` with the branch name you want to use if you are not using the default branch:

        git push -u origin master

6. Verify on GitHub: Refresh your GitHub repository page, and you should see your uploaded folder and files.

Your folder and its contents are now uploaded to GitHub. You can continue to make changes, commit, and push to keep your repository up to date. There are also other ways to upload files and folders to GitHub, such as using the GitHub Desktop client or the command line [3][4]. Additionally, there are many video tutorials available on YouTube that demonstrate how to upload files and folders to GitHub [5][6].
