MaxSez: Never heard the Term “Approach Plate” before! Stop go no further; You need a copy of the Aviators Bible; “The Pilots Handbook of Aeronautical Knowledge” (FAA-H-8083-3B), it’s Free in PDF Form from faa.gov.
If you know that “ Flight Information Publications” (FLIP’s) include the “Plate” Series you may proceed and watch the video and get “airworthy”…
