+## Run
+
+This DIDComm Mediator is composed of two elements, a backend service and a the database.
+The backend service is a JVM application and the database used is MongoDB.
+The backend service is also a web service that have a single page application that will give the final user a invitation page.
+
+### Run localy
+
+Everything can be run with a single command with Docker compose `docker-compose.yml`
+
+First build to docker image with `NODE_OPTIONS=--openssl-legacy-provider sbt docker:publishLocal`.
+The latest stable image version can also downloaded from the IOHK repositories.
+
+### MongoBD
+
+Docker compose would do that for you but if you are running separately or on the cloud like MongoDB Atlas.
+You will need to create the table and indexs before start the backend service. See the file `initdb.js`.
+
+### Deploy
+
+You can easy deploy the image everywhere. We recommend a minimum of 250 mb ram to run the mediator backend service.
