 ### Testing MicroVMs locally
-MicroVMs can be built and run easily on your local host, but they are not persistent!
-For durruti for example this is done by:
+MicroVMs can be built and run easily on your localhost for development.  
+We provide the script ```run-vm``` to handle stuff like development (dummy) secrets, sharing directories, ect. easily.
+Usage examples:
 ``` bash
-nix run .\#durruti-vm
+# run without args to get available options and usage info
+run-vm
+
+# run nextcloud locally with dummy secrets
+run-vm nextcloud --dummy-secrets
+
+# share a local folder as /var/lib dir so that nextcloud application data stays persistent between boots
+mkdir /tmp/nextcloud
+run-vm nextcloud --dummy-secrets --varlib /tmp/nextcloud
+
+# enable networking to provide connectivity between multiple vms
+# for that the malobeo hostBridge must be enabled on your host
+# this example deploys persistent grafana on overwatch and fetches metrics from infradocs
+mkdir overwatch
+run-vm overwatch --networking --varlib /tmp/overwatch
+run-vm infradocs --networking

 In order to test persistent microvms locally we need to create them using the ```microvm``` command.  
 This is necessary to be able to mount persistent /etc and /var volumes on those hosts.
