+### Setup and deploy Interlink's edge service with mock plugin 
+
+Following are the steps to setup and deploy edge service, which offload's a docker container. The virtual K8S node is deployed elsewhere:
+* Make sure to have Docker installed on the target machine
+* Execute the following command: 
+
+        $> sudo usermod -aG docker $USER
+
+* Open and edit the following lines in the script  ``` interlink/docs/itwinctl.sh ``` to update authentication proxy settings
+  * Depending on your network policy, update the port number with the exposed port of your OAuth-Proxy service: 
+
+         --API_HTTPS_PORT="${API_HTTPS_PORT:-7002}"
+  * Set correct the host's PKI credentials (or certificates and private key) path: 
+
+        export HOSTKEY="${HOSTKEY:-/$HOME/hostkey.pem}"
+        export HOSTCERT="${HOSTCERT:-/$HOME/hostcert.pem}"
+  * To generate demo certificates, run the following openssl command: 
+
+        $> openssl req -x509 -sha256 -newkey rsa:4096 -nodes -keyout key.pem -days 11688 -out cert.pem -subj "/C=DE/CN=JSC-INTERTWIN-COMPUTE" -addext "basicConstraints=CA:FALSE" -addext "keyUsage=digitalSignature, nonRepudiation, keyEncipherment, dataEncipherment" -addext "extendedKeyUsage=clientAuth"
+
+        
+* After installation, start the docker-sidecar (or mock plugin)
+
+        VERSION=0.0.1 SIDECAR=docker ./itwinctl.sh start
+* Please check the logs if the services are properly running, they can be found under: ``` /$HOME/.local/interlink/logs/ ```
+* Execute offloading a compute task from application layer and check if the docker container is running, by:
+
+        docker ps -a
+
