How does Code Cloud Warehouse use badges?

questions are as follows

are these badges copied directly from shields.io to url into README.md? Or is it produced by continuous integration tools?
and how are the value statistics of tags like downloads calculated?

I mainly want to beautify the readme.md file of my project. I don"t know if any of my predecessors have used these tags to share their experience.
