You should have some money left for more miners. Make sure they're scouting, not rushing off in Fighters or something. Your teleport receiver should be about done. If you didn't take the Commanding tutorial then you shouldn't be here. Now, place it on a generic asteroid near your Garrison.
Generic asteroids are the plain colorless ones.
Their names start with 'a' followed by some numbers. Now, if you're in a team smaller than 5 members, then go scout. This isn't a scouting guide so dont come to me. Find the enemy's home. If you don't have to scout, tell someone to find the home aleph instead.
