This is how I set up my big wedge tent by myself - 10 wide by 12 long by 8 1/2 high.
I lay the tent out flat on one side. I then stake the corners of the top side tight. I pull the ridge top over to those stakes, and then pull the other side out from underneath until it is about where it needs to be staked. I loosely stake the two corners of it - a little short of where I will end up stretching it tight. I then slide the ridge pole inside the wedge tent, and into place. I then put the front pole through the ridge pole, and stand it up to about where it needs to be. I grab the back pole and then walk into the wedge tent pushing the ridge pole up as I go until I get to the back. While holding the ridge pole up, I then slip the back pole through the ridge pole and stand it upright to about where it needs to end up. I then go outside and re-stake that loosely staked side to it's final position - stretching it tight. If need be, I go back in ad re-adjust the upright poles to get it all to stand square. I then go out and put in all the rest of the stakes.
To take down, I loosen up a few stakes and go inside. I remove the back upright pole, and lower the ridge pole down as I walk to the front. I then remove the front upright pole, and pull out the ridge pole. Then pull all the stakes and fold up the tent.
This works for me - with the big 10x12x8 wedge, and the 6x8x6 foot wedge.
