New Plugin for Site Under Development

Hi
I want to buy a new wp plugin (out-of-the-box) for a website I have already started to develop on Local.
If I buy it, how does the plugin get integrated into my wp admin? Is this a really dumb question (I suspect so).

PGM:

You install a plugin on your site under Local the same way you normally install a plugin on a Live or Staging site from the WordPress Admin screen. You don’t have to do anything special.

“There are no dumb questions; only dumb answers.”
I believe there are also dumb questions. I do not know if yours falls in that category or not.

Hope that helps!
