+# echokit-server Standalone Docker Image
+
+This directory contains a multi-stage Dockerfile for producing a lean runtime image of `echokit_server`.
+
+- **Builder stage** (`rust:1.85-slim`): installs the minimal Rust toolchain dependencies, clones `https://github.com/second-state/echokit_server`, and compiles the project in release mode.
+- **Runtime stage** (`debian:bookworm-slim`): installs the required runtime libraries, copies the compiled binary and default `config.toml`, and sets `RUST_LOG=info` before starting the server with that config.
+
+## Build
+
+```sh
+docker build -t echokit:latest-server .
+```
+
+## Run
+
+Mount your local `config.toml` so the container uses your configuration:
+
+```sh
+docker run --rm -v $(pwd)/config.toml:/app/config.toml echokit:latest-server
+```
+
+The container executes `echokit_server config.toml` by default, reading logs at the `info` level.
