 - **Goal**  
   The user has an application that is deployed to minikube and is looking to improve some aspect of performance of the application. The user specifies an "objective function" in an "Autotune object" that defines the performance aspect of the application that needs to be optimized. Autotune then analyzes the user application, breaks it down into its component layers and provides tunables associated with each layer that can help optimize the user provided objective function.
 - **Steps**  
-  This demo installs Autotune along with Prometheus and Grafana to minikube. It also deploys two example REST CRUD applications, quakus galaxies and springboot petclinic, to the minikube cluster. It then deploys the "Autotune Objects" that define the objective function of the performance tuning that needs to be done for each application.

   It provides a list of URLs that defines the tunables for a user provided slo. See the docs for the definition of the [REST API](https://github.com/kruize/autotune/blob/master/design/API.md) associated with these URLs.

 - **What does it not do ?**  
   It does not kick off any experiments with the tunables (as yet). Stay tuned !!

+  It expects minikube to be installed with atleast 8 CPUs and 16384MB Memory. The default memory limit is 2GB and CPU limit is 2. You can see the current config with the following command:

+  ```
+  $ minikube config view vm-driver
