I think you put the wrong link as that is not linked to any sort of tutorial
But regardless, there are MANY different ways to build yourself to start until you gather the resources for the next.
Me personally, I focus on the following order in terms of level 5 structres (which differ's from George):
1. Gate - because expansion and mobility is extremely important early on
2. Shield - Once I get gate, I personally focus on shield so I can worry less about my defense and focus on offense as well as allow myself a buffer to be able to sleep. Depending on your teams activity level though, this can be moved in terms of importance. My preference though is to make this 2nd priority so I don't get set back after conquering a decent amount.
3. level 5 Res converter - because I use so much energy for scans and sat scans.
4. Nuke - at this point, you should have a decent army with range included in it. Nukes will make you dominant over any armor hoarders (those who made about 100+ armors that your army can't wreck through easily). Also, nice and easy xp gain when you use nukes
5. Level 5 energy I would have energy at level 4 for a while, but as I said, I use a LOT of energy. To me, intel and sight is HUGE. Some other's don't rely on it as much though, so this is my preference
6. Ion - unless you are a heavy booster, this is great for later on in the round, but against player's like George who prioritize nukes last, you don't need ion. Ions should be last ditch imo. Otherwise, you should be active enough to simply dodge nukes otherwise.
