+Our ClickHouse Proxy is a go app runnng on AWS Apprunner. It's only purpose is to receive small batches - or even just single rows - to batch them before sending them in bulk to ClickHouse.
 It does this by implementing the same HTTP interface as ClickHouse and buffering rows in memory, flushing periodically either every few seconds or when the buffer is full.
 
 It's available at `clickhouse.unkey.cloud`.

 Our ClickHouse proxy is fully managed in [unkeyed/infra](https://github.com/unkeyed/infra).
 
 
+## Quickstart
+
+The service is entirely configured via environment variables.
+
+### Environment Variables
+
+<Property
+ name="PORT"
+ type="integer"
+ required={false}
+ >
+  The port to listen on.
+
+  Default: `7123`
+</Property>
+
+
+<Property
+ name="BASIC_AUTH"
+ type="string"
+ required={true}
+ >
+  Username and password in the form `<username>:<password>` (username and password separated by a colon), which will be used to authorize incoming requests.
+
+  Basic auth was chosen because that's what ClickHouse uses and allows to reuse their SDKs.
+  In your sdk, you can specify the url as `https://proxyUser:proxyPassword@host:port` and it will just work.
+
+</Property>
+
+
+<Property
+ name="CLICKHOUSE_URL"
+ type="string"
+ required={true}
+ >
+  The HTTP URL of your clickhouse cluster. Ensure this includes the username and password
+
+  Example: `https://username:[email protected]:8123`
+</Property>
+
+### Running the service
+
+You can run the service either by compiling the go binary via:
+```bash
+cd /apps/chproxy
+go build -o chproxy .
+./chproxy
+```
+
+Or using the included [Dockerfile](https://github.com/unkeyed/unkey/blob/main/apps/chproxy/Dockerfile)
+
+See the [docker compose](https://github.com/unkeyed/unkey/blob/main/deployment/docker-compose.yaml) reference for more.
