Single particle in system?

This might be a stupid question, but I am trying to figure out how to have my system spawn a single particle and then stop spawning others. I have tried playing around with the spawn module, but I can’t figure out how to get it to stop spawning after spawning one. I can’t figure out how to phrase the question well so google has yielded nothing.

Hello Ironic,
Click on the Required part of the emitter, Under duration there is “emitter loops”
Here you can set it to loop only once for instance.

That worked. I knew it was going to be something simple. Thanks for the answer!
