Quick particle Q

Hello Blender Community! I have been away from blender for quite some time now because, well…life. I"ve recently reignited my old blender flame and have a project I’m working on. Forgive me if this is a simple question but like I said Ive been out of the blend game for a while.

I need to have my particles running in reverse. By that I mean I would like have the particles appear to be gathering towards my emitter. I thought I remembered that there was a way to do this?
