How to paint metal door frames

Hi there, 

I am wanting to repaint the metal door frames in my house. Not sure where to start as the instructions on the web seem to all be around wooden door frames. The metal door frames do have chips here and there so not sure if I need to prepare them in another way? 

Thanks so much.

I wasn’t no. I will be now though. I’ll report back once I get back to it.
