How to pin markers on my map?

I am trying to create some hiking maps and want to add markers at specific gps coordinates within the map. My base layer is ESRI World Topo and I have imported some gpx files on top of some trails. I have the gps coordinates of know springs and water sources that I want to add to my map. How do I do this? Thank you in advance.

Edit: I was able to do this by creating an excel sheet and importing it into qgis. Thank yall
