# 03A Explaining What a Product Does

A product description should help someone imagine a useful activity, rather than simply introduce a collection of impressive technical features.
Our example product is a small learning website for adults who want to practice language skills during a busy day.
There is a short introduction on the home page, and there are several lessons that visitors can explore without creating an account.
Each lesson includes a reading passage, a conversation, a vocabulary list, and a few exercises with clear answers.
The main value is the connection between understanding an expression and using it to complete a familiar task.
For example, a learner can read about changing a page and then practice making the same request in English.
The website does not need a complicated interface to deliver that value, but it does need accurate and accessible content.
We explain the available functions with ordinary verbs such as read, listen, save, review, and practice.
When a visitor understands these actions, it becomes easier to choose a lesson and begin a meaningful learning session.
A good description therefore connects the audience, the activity, and the benefit in language that a new user can understand.
The explanation should remain useful even when the visitor has no technical background.
