Grammar matters in whatever type of document you are writing or editing. However, knowing when and how to use the right style and tone of grammar for a information product is an vital part of any project. At the onset, it is important to discuss the tone and the style of grammar to be used. Along with a style guide, using the right number of words, the right tone, and a style of grammar to explain a complex theory or to instruct a user with a task is a crucial first step towards creating a great project piece. Therefore, having a good understanding of grammar, and its many nuances, provides a solid foundation for any technical writer.
