-This model is spatially and mechanistically explicit in simulating a microbial system comprising a large number of hypothetical microbial taxa in terrestial environments. As indicated by the 'py' in its name, DEMENTpy is developed and programmed in Python, based on its predecesor [DEMENT](https://github.com/stevenallison/DEMENT) developed by Steven Allison (promgrammed in R).

 ### Vision
 
-DEMENTpy, initiated with in mind practicing **Real Open Science**, is devoted to 100% OPEN SOURCE and longterm maintanence and development, which, however, will not be limited to ourselves but sincerely seek inputs from the communities that could be as broad as microbial ecology, systems biology, theoretical ecology, etc. Just because of community inputs, please read closely our statement on **policies and rules** of making contributions to DEMENTpy or applying it to your own research.

 ### Structure and Process
 
-This model is built upon its predecessor--DEMENT, an R-based framework initially developed by Steven Allison back in 2012. Except for the programming language change, a series of changes have been made with an overarching goal of making it more readily accessible to the research and teaching communities as broad as microbial ecology, theoretical ecology, and ecosystem ecology, as well as biology. This model simulates processes ranging from degradation of substrates through microbial processes encompassing uptake, metabolism, mortality, reproduction, and dispersal in a spatially explicit, mechanistically explicit fashion. For more detailed information about DEMENTpy, we refer readers/users temporarily to an [Appendix](https://github.com/bioatmosphere/microbiome-drought-legacy/tree/master/writing) of the 1st manuscript applying this model. An actual documentation is under conceiving.
