# Welcome to Paragon Materials Paragon Materials is a companion to the Paragon Design App and allows you to customize the lumber, plate, and hanger options available while designing trusses. Every Component you create has both a Lumber List and a Plate List that determine what materials are available when designing it. When you Upgrade and Analyze a Component, the lumber will be upgraded using Lumber Types from the Component's Lumber List and plates will be upgraded using plates from the Component's Plate List. {% embed url="" %} --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
