This layer of oil will help provide a good seal and make removing the filter at the next oil change easier. Wipe off the oil filter threads and contact area on the engine with a clean rag or towel.

The engine oil dipstick is located on the right side of the engine and has a yellow handle. Remove the dipstick, wipe it off with a clean rag or towel, reinsert it, and remove it again. Read the initial oil level. It should be somewhere in the crosshatched region. It is acceptable for the level to be slightly high, since it hasn't filled the oil filter and other nooks and crannies of the engine yet.
