The bottle is what is called a "squeeze n measure". Basically the small cup at the top is a measuring cup. Remove the top off of this cup and also remove the seal. Squeeze the large main bottle with one hand - and the chemical will flow into the small cup. Squeeze until you get the desired amount, then pour this into the sprayer you are using and add the appropriate amount of water. Then replace the cap on the bottle and store it in a safe place.
