Please don't use sudo pip install as it can mess up your global Python. The recommended way to install Python packages is in a virtual environment. You can use https://github.com/pyenv/pyenv to install the Python version you want, and create a virtual env by following this guide.

Additionally, you need to pass the name of the markdown file for your slides when invoking present:

$ present slides.md

I'll read that as you don't know how to create a pip package. Thanks.

I think you're getting a syntax error for the f-string because you're using a Python version less than 3.6.

I'll read that as you don't know how to create a pip package. Thanks.

What would be the best way to create one? If you can give me some pointers, I can help solve your installation use-case better.
