@dhuseby : HI Dave. Thank you. This is a great update to the py-libp2p documentation! 🎉

• The explicit listing of dependencies, along with direct links to their official sources, makes it much easier for developers to get started.

• The inclusion of both Debian Linux and MacOS installation commands ensures broader accessibility.

• Adding instructions for both virtualenv and Python3 venv is a thoughtful touch, giving developers flexibility in setting up their environments.

• The MacOS-specific build instructions for linking against GMP are particularly useful and help prevent common setup issues.

I will try the changes on Debian and MacOS machine (3 different OS versions) and will merge the changes by the maintainer's call tonight. Appreciate your effort.

Overall, this is a well-structured and user-friendly improvement that enhances clarity and streamlines the onboarding process for new contributors. 🚀👏
