 This repository holds the Functionally Assembled Terrestrial Ecosystem Simulator (FATES).  FATES is a numerical terrestrial ecosystem model. Its development and support is primarily supported by the Department of Energy's Office of Science, through the Next Generation Ecosystem Experiment - Tropics ([NGEE-T](https://ngee-tropics.lbl.gov/)) project.
 
 For more information on the FATES model, see our [wiki](https://github.com/NGEET/fates/wiki) and [technical documentation](https://fates-docs.readthedocs.io/en/latest/index.html).
 
+## Vegetation Management Module
+
+This version of FATES includes the Vegetation Management Module (VM), a extension that allows the simulation a range of realistic vegetation management activities. Consult the [VM documentation](https://joshuarady.github.io/VegetationManagement/) for further information on installing and using the Vegetation Management Module.

 The FATES team maintains compatability of the NGEET/FATES master branch with the **CTSM fates_next_api** branch.  Since the FATES team uses this branch for its internal testing, this compatability is tightly (immediately) maintained and these two should always be in sync.  However, CTSM master may become out of sync with FATES master for large periods (months) of time.
 
+The Vegetation Management Module requires a specific variant of CTSM. Consult the [VM documentation](https://joshuarady.github.io/VegetationManagement/) for installaiton instructions.
