A group could present instructions on how to get started receiving, composing, and saving messages with Pine. Your most important assignment in 3020, by the way, will be an expanded, more comprehensive set of instructions in the form of a manual. You could do the manual on the same general topic as the instructions. The formality of your style should match your subject and audience. Instructions are marked by commands, that is, sentences that begin with verbs.
Commands save words and directly engage the audience that is interested in the process.
An introduction should mention the procedure you will describe, supply an overall description of the process, state why the process is an important one for the audience, and encourage the audience to read the instructions to follow. Preliminary warnings might also be appropriate. If, for example, a person performing the procedure must wear certain articles of clothing, warn the audience that these must be obtained and put on first. These steps can be headed or numbered or bulleted or marked with a wingding of some kind. But unplug the unit first.
