The LSST Software User Guide will document the high-level design of the LSST pipelines, how to install them, how to run them, and how to use them to develop your own data reduction pipelines (i.e., what modules/APIs are present and appropriate to use under what circumstances). This document will be geared towards the end-users (e.g., Level 3, Science Collaborations) and operators who primarily need to run the code, and also towards developers and advanced users who both need to know how to run it and build on top of it

The LSST DM Developer Guide will document the processess and capabilities available to LSST DM staff developers. This will include what machines are available, the development procedures for planned changes (tickets, reviews, merging, etc.), how continuous integration operates, data challenges, etc. This will be the second document a new LSST/DM developer will want to read.
