Getting Started
You should first build six more SCVs (ten total). After each oneis made, make it gather minerals. The second to last one make build a barracks. Then make the last one make a supply depot on one side of your entrance. That one should finish before the barracks so, make anouther supply depot on the other side. The barracks will finish shortly after so lift it off and land it between the two supply depots. Now build a bunker and train four marines to put in it and a few more SCVs. Make the first SCV build a refinery and the second mine minerals If you only have one gyser, make the next SCV mine gas, if you have multiple gysers, make the next SCV build anouther refinery. Also place the marines in the bunkers and build an academy. Build three more SCVs for mining minerals and have three SCVs at each refinery. Also build a comsat station and research stim packs. After you have enough energy in your comsat station, scan all of the start locations for your enemy. Now you should be racking in the money.
Building Your Attack Force
Build four more barracks and make them all build (in this order) four marines and one medic. Repeat this step for each barracks at least nine times. Until you have over one hundred marines (at least 5 times for each.
Expansions
While building your attack force, you should also expand. You just have to remember to always defend your expansions. If you dont and someone attacks the expansion, they will probably build there.
Attack
Assign your marines to groups and stim all of them before you enter the base. Keep the medics nearby so they can heal the marines when they are stimed. Attack the enemy base head on and after a few minutes, the enemy base will be trampled by millions of rampaging marines.
