Want to start podcasting... what Equipment?

I have a go pro hero 5 and a Blue Yeti microphone. Not 100% set on audio AND video... may start with audio and add video later.

What additional equipment or software will I need to get started at the entry level?

Anyone?

Just make sure you use a mic screen. It helps get rid of the hollow sound and the little sounds you hear when you listen to something on, say, a tape recorder. For video, just make sure that, if you have a self adjusting camera, you don't do the podcast in a place with fluctuating light sources.
