Monogame PipelineManager Class

Hi Guys, I have been using the PipelineManager class recently, I used the Methods: Build, Register, and process. I want to know more about what they do, I saw the source code but couldn’t understand well, can any one briefly state what each of the following functions do?

1- RegisterContent(…)
2- BuildContent(…)
3- ProcessContent(…)
4- CleanContent(…)

Thanks!

Can anyone in this forum respond? :frowning:
