Answer:
to inform
Step-by-step explanation:
Something that is technical is something that is "relating to a particular subject, art, or craft, or its techniques". A technical direction is a direction that is related to a particular subject. It's about a craft or the technique of that particular subject. It is teaching you how to deal with it, so it's not meant to deceive, persuade, amuse, or describe. It's meant to inform.
