Dig, align, and finish the job

Dig an 8"-diameter hole at least 6" deeper than your area's frost line for each 4x4 post, using a power auger, hand auger, or post-hole digger. A 6x6 post requires a 10"-diameter hole. Shovel a 6" layer of gravel into the hole to provide drainage. Now, put the strings back on the batterboards, but move them toward the outside of the layout by one-half the post thickness. Set each post in its hole, and move it until the outside edge lines up with the string. Attach two braces to adjacent sides of the post with screws, and drive a stake next to each brace. Use a level to make sure the post is plumb -- check adjacent sides -- and fasten the braces to the stakes with screws. When everything lines up, add water to premixed concrete, and fill the holes.

My 1910 Craftsman house was reworked in about '78, and the wooden porch was taken out (rotten) and replaced with concrete. The 12x12 redwood posts were sunk into the concrete deck of the porch as the roof was re-assembled. Now one post is about 8" lower than the other, rotting in the hole, since there's nowhere for rain to go.

RogersI2 raised the red flag about sinking wood in concrete. It it the WORST POSSIBLE solution to fixing a deck/fence post to the ground. Even steel posts when sunk into concrete will begin to rust at the surface of the concrete where the moisture from the elements oxidises the steel and rots the wood in a surprisingly fast pace. As RogerI2 said, use GALVANIZED embeds in the concrete and SEAL THE CONCRETE at the interface with the embed for a long-lasting installation.

A comment about "one call" numbers. You can now simply dial "811" anywhere in the country in order to reach your nearest one-call center. There is no longer a need to remember lengthy telephone numbers.

Great article. Clear concise and to the point. If one can not follow this, they should probably farm the job out to someone more qualified.
