+#### Demo Notes
+EVerest is designed with embedded applications in mind. To illustrate this, we've imposed maximum CPU usage and RAM constraints of 100% (1 core) and 1024MB, respectively, in each of the demos. Even on modest desktop hardware, these constraints should only result in slightly longer boot times.
+The resource constraints for a demo can be changed in its Docker Compose file (the file downloaded in "STEP 1" below).

 ### STEP 2: Interact with the demo
 - Open the `nodered` flows to understand the module flows at http://127.0.0.1:1880
 - Open the demo UI at http://127.0.0.1:1880/ui
