Badges are small icons showing some pieces of information such as versions, test results, downloads, license. See the first line of the Python package setuptools's README file which shows its current PyPI version, supported Python version, etc.
shields.io is one of the services that help you
to customise your badges. For example, it provides a list of version
badges, so when you embed
https://img.shields.io/pypi/v/<package> into your README file like
this:
[](https://pypi.org/project/pysarplus/)
It will show:
- Examples
- GitHub badges
