You can check off each step to keep track of where you are in the installation process. Keep the groove edge toward the starting corner, and the tongue edges toward your work direction. Face nail the first plank even if you plan to glue the other boards. Measure and fit next boards carefully. The last board may have to be trimmed to fit into a corner.
Angle trim the board's corner edge slightly with a block plane.
Install your planking with the wide portion of the board away from the wall.
