French Drains are installed by digging a trench deep enough to burry your pipe at least 4 inches below grade. The slope of the trench should be 2% (or 1/4 inch per foot) to be able to move solids that collect in the pipe. You will want a clean-out and good area to discharge to along with good draining material to pack in around your pipe so water can get into the pipe easily.
