One GitHub repository

Hello everyone! I want to create multiple projects for programming portfolio. I want to store them on GitHub. I know how to create individual repository for one project. But how can I create one repository where I will store all my projects?

Generally, you don’t. The common use is one repository per project.

There are some advanced examples of what’s called a “monorepo”, but those aren’t quite as common.

If you are new to git and GitHub, stick with one repo per project for now.
