+## Update mode
+DRE can run in two different modes.
+Each of them listens on gateways notification and registers new contracts, but upcoming new interactions are handled differently. 
+
+#### Poll
+Node fetches interactions directly from gateway in time intervals.
+Interaction are grouped and executed sequentially.
+This is the default mode.
+
+
+#### Subscription
+Node listens on new interactions events and evaluates contracts immediately after every interaction.
+This offers a faster contract evaluation and serves the latest contract state 
+
+Update mode can be set up using env config
+``UPDATE_MODE='poll'`` or
+``UPDATE_MODE='subscription'``
