Step response to an impulse response

[EeCe]

Hi all,

I'm having a lot of trouble understanding this step response:

Problem statement:

Consider an LTIC system with impulse response given by: h(t) = u(t) - u(t-2)

Sketch the step response s(t).

I've already sketched h(t)...but,
I know that the step response is found by integrating h(t) with respect to tau over the range -∞ to t. I know this is not hard, but for some reason I'm just having trouble figuring out what to do, and my text doesn't cover the step response at all (probably because it's so easy).

Any help if how to find the step response would be appreciated. Thanks

Well, I figured out on my own.
