-## OPNSense demo
+# OPNSense Demo
 
-Download the virtualbox snapshot from {{TODO URL}}
+This example demonstrate how to manage an Opnsense server with harmony.
 
-Start the virtualbox image
+todo: add more info
 
-This virtualbox image is configured to use a bridge on the host's physical interface, make sure the bridge is up and the virtual machine can reach internet.
+## Demo instructions
 
-Credentials are opnsense default (root/opnsense)
+todo: add detailed instructions
 
-Run the project with the correct ip address on the command line :
+  - setup the example execution environment
+  - setup your system configuration
+    - topology
+    - scores
+    - secrets
+  - build
+  - execute
+  - verify/inspect
+
+## Example execution
+
+See [learning tool documentation](./scripts/README.md)

+# Virtualized Execution Environment for Harmony
+
+Scripts included in this directory have 3 purposes:
+
+  - automate initial setup of localhost or VM (nested virtualization) for this example
+  - prototype a solution for an 'OpensenseLocalhostTopology'
+  - prototype 
+
+This exprimentation aim to find an approach suitable for using harmony on virtualised execution environment such that:
+
+  - it straights forward for a user with minimal knowledge to start testing harmony
+  - installation and execution have **minimal impact on the user desktop**
+
+## Usage
+
+### Installation
+
+1. download this directory
+2. add this directory in your PATH (example `. setup`)
+
+
+```
+# show help page
+harmony-vee
+
+# show active configurations
+harmony-vee config
+
+# show what will be modified at installation
+harmony-vee install --dry-run
+
+# install
+harmony-vee install
+
+# show what will be modified at unistallation
+harmony-vee uninstall --dry-run
+
+```
+
+### Create and start a new Virtual Execution Environment
+
+
+```
+# Create a HVEE to test opnsense_score
+harmony-vee init opnsense_score
+
+# List existing HVEE
+harmony-vee list
+
+# Show HVEE information including devices ip and vault type/location
+harmony-vee show opnsense_score
+
+# Start/Stop a HVEE
+harmony-vee stop opnsense_score
+
+
+# Destroy a HVEE instance
+harmony-vee destroy opnsense_score
+
+```
+
+
+### Variable d'environnement
+
+```
+## directory containing harmony-ve data
+# HVE_ROOT=~/.harmony-ve
+
+## OPNSENSE SRC
+# main mirror
+# HVE_OPNSENSE_URL=https://pkg.opnsense.org/releases

+## Network
+# HVE_NETWORK_LABEL=harmony

+
+
+## Remarks
+
+  - A nested VM setup could be safer
+
+
