Create and maintain a requirements.txt file, updating it continuously as new libraries are added.

Make a workflow to automate
If you're using Python and want to automate this, you can run:
pip freeze > requirements.txt
And each time you install a new package (e.g., pip install requests), just re-run the command to update the file. Alternatively, you can manually append new libraries to the file as you go.
