 * _concore_: The CONTROL-CORE protocol, known as _concore_, allows modular simulation of controller and PM nodes to run on different operating systems, computing platforms, and programming languages. [This repository](https://github.com/ControlCore-Project/concore/) consists of _concore_ source code. The _concore_ documentation can be found [here](https://control-core.readthedocs.io/en/latest/index.html). A _concore_ study can be developed from programs written in different languages. That means, _concore_ facilitates a seamless communication across codes developed in different languages that it supports, through its simple file-based data sharing between the programs.
 
-* _concore_ Editor: This is the front-end for CONTROL-CORE. We forked [DHGWorkflow](https://github.com/ControlCore-Project/DHGWorkflow), a sibling project we developed, and extend it as the _concore_ Editor. Please check out the [dev branch](https://github.com/ControlCore-Project/DHGWorkflow/tree/dev) for the _concore_ Editor.

 * _Mediator_: The [Mediator](https://github.com/ControlCore-Project/mediator) allows the CONTROL-CORE studies to be distributed and run, rather than having all the programs that construct a study to be run just from a centralized location.
