Have a look at the Contribution Guide in the repository.
There are detailed instructions on how to get the project set up locally and how to contribute.
Note that currently, development seems only to be supported for Mac and Linux, not for Windows. Also, pull reguests only are accepted for a few libraries, not including material3.
You will have to install a repo tool, which has similar capabilities like Git. Also, you will install a specific version of Android Studio for library development.
The guide also explains how to get the Previews working.
If you only want to inspect some code, you could try to simply clone the repository in Android Studio like this:
Android Studio -> New Project -> Import existing project from Version ControlThen enter the URL from the
Codebutton in Github in Android Studio:
