Summarize this article:

You can't marinate the entire chicken all at once. You want to marinate each strip of chicken separately so that each piece you eat will have a strong flavor. As you put the chicken pieces into the marinade turn them front and back so that the marinade gets on both sides. You don't need to roll it around in there, just make sure no part of the chicken piece is dry. Otherwise you risk the chicken piece drying out in the fridge. Cover the bowl with plastic wrap, and refrigerate for a minimum of one hour and up to overnight. This will allow the flavor to really soak into the chicken. If you don't refrigerate the chicken you risk it going bad, so don't leave the marinade out on the counter. The longer the chicken marinates, the more tender and flavorful it will be. Try to plan ahead.

Summary:
Make sure you have cut up your chicken into pieces. Place your cut up chicken pieces in the marinade. Refrigerate the chicken and marinade.
