The document discusses building low-fidelity wireframes. It recommends starting with wireframes that are lower fidelity to focus on the customer experience without visual design details. The document also recommends building wireframes from the "inside out", prioritizing the most important screens and elements first based on customer usage and critical functionality. It provides an example of wireframing the destination entry area first for a ride-hailing app since that is central to the app's purpose. The goal of wireframes is to communicate and clarify the customer journey through a product in its early stages.
