+# Tutorial
+
+- [Quick start](quickstart.md)
+Start here to setup download software and configure your development environment.
+- [Part 1](part1.md)
+An introduction to detecto description starting with a simple detector. This tutorial shows how to add new parameterized detectors to a library of generic detectors (NPdet).
+- [Part 2](part2.md) 
+
+This tutorial is broken in to multiple parts.
+
+* Preface for the new programmer
+* Part 0a: Configuring your running environment
+* Part 0b: Configuring your development environment
+* Part 1: Simple Detector Example
+* Part 2: Extending Detector Geometry
+* Part 3: Adding a new detector
+* Part 4: Detector digitization, volumes, and segmentation 
+* Part 5: Event reconstruction
+

+# Welcome
+This tutorial is meant to prepare you to contribute to the simuliation toolkit for the EIC.
+The tutorial is not meant to be a representation of the final software workflow, but to put enough pieces
+together to do the work required.
