Zerg question!!!

If you’re Terran, IMMEDIATELY set your first SCVs to harvest minerals. Build another. Set him to harvest. Once you’ve got 8 SCVs harvesting, set your ninth and tenth to build Supply Depots. As soon as the FIRST Supply Depot is complete, send that SCV to mine. Simultaneously, build 2 more SCVs, whose purpose is to finish building units. Once the second Supply Depot is complete, send that SCV to mine. The two new SCVs you were building should be done by now; set them to build a Barracks and another Supply Depot. As soon as the one building the Supply Depot is done, set him to mine TEMPORARILY. As soon as the Barracks is done, send him to build a bunker, while you tell the Barracks to start popping out Marines. Bring back the previous SCV that you temporarily have mining, make him build another bunker, and then as many Supply Depots as you can. If you’re running low on minerals, remember to build more SCVs to mine. Ideally, you want to build 3 Bunkers, have each one FILLED with Marines, then a few spare marines. Build an Academy, then some Firebats, and you’ll be taking down ‘lings like they’re nothing.
