 See the [System Requirements](../INSTALL.md) for installing / using BLT. It is strongly urged that you use a Mac for local development, although certain versions of Linux and Windows 10 can also be used. Other operating systems ***should not*** be used for BLT development.
 
 ## Enterprise Web Development
-### Virtual Environment
+### Development Environment
+BLT can be operated on any "LAMP" stack that will run Drupal. Acquia provides several tools for this, but they are optional.
 #### [DrupalVM](https://www.drupalvm.com/)
 This project aims to make spinning up a simple local Drupal test/development environment incredibly quick and easy, and to introduce new developers to the wonderful world of Drupal development on local virtual machines (instead of crufty old MAMP/WAMP-based development).
+#### [DevDesktop](https://www.acquia.com/products-services/dev-desktop)
+Acquia Dev Desktop is a free app that allows you to run and develop Drupal sites locally on your computer and optionally host them using Acquia Cloud. Use Acquia Dev Desktop to evaluate Drupal, add and test other Drupal modules, and develop sites while on a plane or away from an internet connection.
