Instructions is the most common term, and may be synonymous with directions- step-bystep guidance on how to perform a specific task or function. A manual or guide will include many sets of instructions. Used alone, however, “instructions” can refer to the simplest instructive manuscript- push cap and twist to open, use other door (similar to Turkish ones such as lüzümsuzsa söndür, çimlere basmayın, iyice karıştırın).
