# What is Skyline?
Welcome to Skyline, Benevity's design system.
This site contains everything you need to know about the simplest, fastest way to build user interfaces that look and feel like they belong in the Benevity ecosystem of Purpose-driven software (opens new window). Save time and avoid reinventing already solved problems by tapping into this resource of shared learnings and best practices of common patterns within our software.
Skyline really shines during the Design, Development and Testing phases of our Software Development Life Cycle.
UI and UX Designers use Figma and this Documentation to make decisions about the best approach to achieve the goals of a project.
Web Developers consult the Figma assets to see which pieces are Skyline and which need to be custom-built, and leverage Component examples and requirements as-needed.
Software Testers consult the documentation site to understand expected component behaviours and markup for creating automated testing baselines.
