Making an enemy class for monogame c#

I have been given the task to create an enemy class as well as an enemy manager. I am completely confused as to how I will attempt this. these classes will be added into one group project with my other group members. I need to include things such as enemy health, the sprite itself, animations etc. I am new to using Monogame and c# so it would be appreciated that any help given is in an extremely simple form.
