We started in the closet s a test. If you need to cut the plywood to fit the space, place the edges you cut towards the edge of the wall as the cuts you make will not be as straight and clean as the factory edges.
Once you have made your cuts lay down the plywood sheets the way you want them as a test. If everything looks right you are ready to attach the plywood to the subfloor.
Use the construction adhesive on the liberally on the "bad" side of the plywood (the side without the nice woodgrain). Once glued set the plywood on the subfloor and nail it down. I used a lot of nails as I wanted it to be solidly affixed and I did not want to have to wait for the glue to dry to lay down more sheets.
First I nailed down the corners and placed a nail in the middle.Then I placed the nails in columns that ran down the lenght of the sheet, each collumn of nails abound 4-6 in from the next. I did not measure, I just eyeballed it.
I put down the plywood in sheets running longwise next to each other. There was a small strip on one side of one wall that required me to cut lengths of plywood (about 4 in" wide stops of 8').
At the end of the room I had to cut the plywood to fit. The pictures show all of this.
