 The most valuable component for better integrating models with *basically anything else* is a standard language for communicating the structure of those models. That language is `XMILE <http://www.iseesystems.com/community/support/XMILE.aspx>`_. The draft specifications for this have been finalized and the standard should be approved in the next few months.
 
-A Python library for analyzing system dynamics models called the `Exploratory Modeling and Analysis (EMA) Workbench <http://simulation.tbm.tudelft.nl/ema-workbench/contents.html>`_ is being developed by `Erik Pruyt <http://www.tbm.tudelft.nl/en/about-faculty/departments/multi-actor-systems/policy-analysis/people/erik-pruyt/>`_ and `Jan Kwakkel <https://github.com/quaquel>`_ at TU Delft. This package implements a variety of analysis methods that are unique to dynamic models, and could work very tightly with PySD.

-An excellent JavaScript library called `sd.js <https://github.com/bpowers/sd.js/tree/master>`_ created by Bobby Powers at `SDlabs <http://sdlabs.io/>`_ exists as a standalone SD engine, and provides a beautiful front end. This front end could be rendered as an iPython widget to facilitate display of SD models.
+An web-based app called `Simlin <https://simlin.com/>`_ created by Bobby Powers exists as a standalone SD engine. Allows building models and exporting them to XMILE output.

+`Pylint <https://pylint.readthedocs.io>`_ is a module that checks that your code meets proper Python
 coding practices. It is helpful for making sure that the code will be easy for other people to read,
 and also is good fast feedback for improving your coding practice. The lint checker can be run for
 the entire packages, and for individual Python modules or classes. It should be run at a local level
