Any tips on how to shave my legs?

I’m really sorry if this isn’t the best place for this but I don’t know where to go. Im a trans girl (I think so, at least) and I only started recently to shave my legs. Im using those plastic three blade dollar store razors, for the record, but I’ve been wondering if there’s anything I should know about shaving your legs. I know to shave against the grain, to let my legs soak in water a bit before, but other than that, is there anything else I should know about? Any tips would be really really appreciated. Thanks you so much :]
