-# go-qubic-nodes
+# The Qubic nodes service
 
-Http service for fetching reliable qubic node information
+The purpose of the `qubic-nodes` service is to continuously check node reliability and provide, upon request, a list of reliable nodes. 
+
+## Building from source
+
+```shell
+go build
+```
+
+## Running the service
+
+### Configuration
+The service can be configured either by CLI parameters or environment variables.
+The current configuration will be printed at startup.
+
+#### Required parameters
+```shell
+QUBIC_NODES_QUBIC_PEER_LIST:                "5.39.222.64;82.197.173.130;82.197.173.129"
+```
+
+#### Optional parameters
+```shell
+QUBIC_NODES_QUBIC_EXCHANGE_TIMEOUT:         (default: 2s)
+QUBIC_NODES_QUBIC_MAX_TICK_ERROR_THRESHOLD: (default: 50)
+QUBIC_NODES_QUBIC_RELIABLE_TICK_RANGE:      (default: 30)
+
+QUBIC_NODES_SERVICE_TICKER_UPDATE_INTERVAL: (default: 5s)
+```
+
+### Docker (recommended)
+A `docker-compose.yml` file is provided in this repository. You can run it as-is using `docker compose up -d`.
+
+> It may be necessary to configure an up-to-date list of peers if the service fails to start.
+
+### Standalone
+
+Export the required environment variables:
+```shell
+export QUBIC_NODES_QUBIC_PEER_LIST="5.39.222.64;82.197.173.130;82.197.173.129"
+```
+You can now start the service:
+```shell
+./go-qubic-nodes
+```
+
+## Available endpoints
+
+### /status
+```shell
+curl http://127.0.0.1:8080/status
