When writing instructions for users who might see the instructions frequently, putting an introduction like that, especially with the locally-relevant data buried, is not helpful. Instead, their terse instructions, written in a familiar and easily-parsable format are ideal. Placing a "What is this?" link afterward that opens[1] to more detailed instructions is how you should approach this. [1] Through whatever mechanism is most appropriate for your audience. I'd suggest a tooltip by default.
