# 1. Introduction

This document defines the requirement for the Phylogeny Explorer program that is being developed. The purpose of this document is to represent the system requirements in a readable way so that clients and stakeholders can understand them and verify them for correctness but with enough detail that developers can design and implement a software system from them. 

This document doesn’t address project issues such as schedule, cost, development methods, development phases, deliverables and testing procedures. Those are addressed in a separate project overview.
