+# Replica Service
+
+The docker-compose project runs a local replicate l2geth.
+
+## Prerequisites
+
+\- docker
+
+\- docker-compose
+
+## Start replica service
+
+### Configuration
+
+Replace `INFURA_KEY` with your own key in [docker-compose-replica-service.yml](./docker-compose-replica-service.yml).
+
+### Start the docker
+
+Start the replica service via:
+
+```bash
+cd ops/
+docker-compose -f docker-compose-replica-service.yml up
+```
+
+This will pull the two images from docker hub:
+
+* [`data-tranport-layer`](https://hub.docker.com/layers/156092207/omgx/data-transport-layer/production-v1/images/sha256-07d4415aab46863b8c7996c1c40f6221f3ac3f697485ccc262a3a6f0478aa4fb?context=explore): service that indexes transaction data from the L1 chain and L2 chain
+
+* [`replica`](https://hub.docker.com/layers/157390249/omgx/replica/production-v1/images/sha256-fc85c0db75352a911f49ba44372e087e54bd7123963f83a11084939f75581b37?context=explore): L2 geth node running in sync mode
