Introduction

The primary source code management system for the Mu2e Offline software is a git repository that is hosted on the Fermilab redmine site. Other Mu2e software is managed using other source code management systems.

Please follow these commit instructions for the mu2e conventions on commits.

The BTrk UPS product, which contains our kalman fit code, is stored in the BTrk github repo

Quick Start

Please also see the basic code recipe for an introduction to setting up the environment, checking out code and building.
