 `VPLanet` is a community project. We're happy to take pull requests; if you want to create one, please issue it to the *dev* branch. Soon we will include tutorials on adding new input options, governing variables, and modules. It's a platform for planetary science that can grow exponentially, either by adding new physics or by adding competing models for clean comparisons.
 
-The [examples/](examples) directory contains input files and scripts for generating the figures in Barnes et al. (2019) and all subsequent module descriptions. The [Manual/](Manual) directory contains the pdf of Barnes et al. (2019), which describes the physics of each module, validates each module against observations or past results, and uses figures from the [examples/](examples) directory.

 An ecosystem of support software is also publicly available. In this repo, [vspace/](vspace) contains scripts to generate input files for a parameter space sweep. [bigplanet/](bigplanet) contains scripts to store large datasets in HDF5 format and quickly calculate summary properties from an integration, like change in surface temperature. In a separate repository is [vplot](https://github.com/VirtualPlanetaryLaboratory/vplot), which consists of both a command line tool to quickly plot the evolution of a system, and also matplotlib functions to more easily generate publication-worthy figures. Finally, we recommend using [approxposterior](https://github.com/dflemin3/approxposterior) to quickly obtain posterior distributions of model parameters.
