The Simulation Tools Documentation Ecosystem

For most elements documented in the Simulation Tools Handbook there are three types of documentation:

1. The user guides presented here in this RDox Simulation Tools Handbook,

2. The Code Repository presented in GitHub, which also hosts example notebooks, and

3. The Developer Documentation in ReadTheDocs that is updated as code is updated. 

Each of these forms of documentation provide insight into the functioning of the simulation tools. The user guides in this Simulation Tools Handbook are helpful for getting started with the tools and applying them to science projects, the code repositories are helpful for anyone who needs to view the code or basic examples, and the developer documentation has the most up-to-date explanation of installation instructions and specifics about all the available parameters and other code details. 

The Table of the Status and Locations of Simulation Tools Documentation provides a succinct description of each tool and catalogs the various forms of documentation available for each.
