+# Distributed
+
+1. Create user `demo` with password from `AHRIMAN_PASSWORD` environment variable.
+2. Setup repository named `ahriman-demo` with architecture `x86_64`.
+3. Start web server at port `8080`.
+4. Start two workers.
+5. All updates triggered by the web server will be passed to workers.
+6. All updates from worker instances are uploaded to the web service.
+7. Repository is available at `http://localhost:8080/repo`.
+
+Note, in this configuration, workers are spawned in replicated mode, thus the backend accesses them in round-robin-like manner.
