+## Install
+
+Use `example_config.toml`. The settings that are important to look at are `listen_host`, `listen_port`, `data_dir`, `api_client_user_agent` and `origin`.
+
+The executable is self-contained. Serve it behind any reverse proxy. The process must have read/write access to `data_dir`, where the repositories will be stored.
+
+```bash
+blindforge config.toml
+```
