Boilerplate requirements

What is a boilerplate?

In computer programming, boilerplate code or boilerplate refers to sections of code that have to be included in many places with little or no alteration. It is often used when referring to languages that are considered verbose, i.e. the programmer must write a lot of code to do minimal jobs.

For instance, a lawyer may give you a five page contract to sign, but most of the contract is boilerplate — meaning it’s the same for everyone who gets that contract, with only a few lines changed here and there.
