+## Pre requisites
+1) Compile docker images with `make build_docker_all`
+2) Run docker compose
+
+## Instructions 
+
+This scripts allow the user to run a huge amount of beacons process as well as run clients to fetch and test generated randomness.
+You should run `beacons.sh` script and wait until it finishes. After you will be able to run `clients.sh` script.
