What are some steps to making a minimap/radar

I’m trying to figure out how to implement a Minimap or Radar into my game. What are some ways to get started or the possibly ways to create one?
I’m trying to recreate the minimap using the “Strategy Game” example, but im not sure how the minimap is capturing at the “Z” distance and facing ? degreees. and how to display in in the corner.

This Video show how to do this!

And, if you need the minimap camera show other angle (top view, for example) you only need to change the Blueprint camera position in the viewport, it´s really easy…See this tutorial.

I have created radar tutorial. Maybe it will be helpful:

Nice one, thank you very much!
