 ## Submitting Programming Activities
 
 We will use [GitHub](https://github.com) as a class submission portal for each programming activity. To get started with GitHub, please set up a project repository, initiate a README, and create two folders where you can upload completed notebooks and reflections for each programming activity.

-### GitHub Instructions
-
+**GitHub Instructions**:
 1. **Create a new repository**: Go to GitHub and create a new repository for your project. Name it appropriately, like `social-coding-portfolio`. Accept the option to initiate a `README.md`, which should serve as a project overview with an outline of its purpose, its structure, and related information. 
 2. **Create two folders**: (i) `Notebooks` for Jupyter Notebook files and (ii) `Reflections` for Markdown reflections. [Click here](https://stackoverflow.com/questions/12258399/how-do-i-create-a-folder-in-a-github-repository) for guidance on how to set up folders on GitHub.<br>
 3. **Upload reflection and notebook**: Upload each submission as two files (one `.ipynb` in `Notebooks` and one `.md` in `Reflections`) and commit them with semi-descriptive messages.<br>
