+# Clio official docker image
+
+[Clio](https://github.com/XRPLF/clio) is an XRP Ledger API server optimized for RPC calls over WebSocket or JSON-RPC.
+It stores validated historical ledger and transaction data in a space efficient format.
+
+This image contains `clio_server` binary allowing users to run Clio easily.
+
+## Clio configuration file
+
+Please note that while Clio requires a configuration file, this image doesn't include any default config.
+Your configuration file should be mounted under the path `/opt/clio/etc/config.json`.
+Clio repository provides an [example](https://github.com/XRPLF/clio/blob/develop/docs/examples/config/example-config.json) of the configuration file.
+
+Config file recommendations:
+- Set `log_to_console` to `false` if you want to avoid logs being written to `stdout`.
+- Set `log_directory` to `/opt/clio/log` to store logs in a volume.
+
+## Usage
+
+The following command can be used to run Clio in docker (assuming server's port is `51233` in your config):
+```bash
+docker run -d -v <path to your config.json>:/opt/clio/etc/config.json -v <path to store logs>:/opt/clio/log -p 51233:51233 rippleci/clio
+```
