We should add a Code of Conduct to our project. It's important for setting the tone for a respectful and inclusive community. This will guide everyone's interactions and help handle any issues that arise.

Steps to add the Code of Conduct:

1. Choose a simple, standard template like the Contributor Covenant.
2. Add it to our project in a CODE_OF_CONDUCT.md file.
3. Make sure everyone is aware of it.

By having a Code of Conduct, we'll create a better environment for all contributors.
