 ### openethereum-node-status
 
-> ⚠️ WIP
-
 A tiny stateless service to return health status and useful metrics from OpenEthereum/Parity nodes. Requires the [following API's](https://openethereum.github.io/JSONRPC) to be enabled:
 
 - eth
 - parity
 
+#### Usage
+
+Default config:
+
+```bash
+RPC_ENDPOINT=https://core.bloxberg.org
+SERVER_POINT=80
+DEBUG_ENABLED=false
+```
+
+Build and run:
+
+```bash
+make build
+docker build -t node-status:latest .
+docker run --rm -p 5555:80 node-status:latest
+```
+
+Pre-build Docker image is available at `docker.grassecon.net/devops/node-status:latest`
+
+Use with any uptime tracker and/or metrics scrapper.
+
