+# Lab 1 Scenario
+
+This directory contains the Lab 1-specific services and configuration for MiniCorp.
+
+The reusable Linux network topology is provided by:
+
+```text
+shared/minicorp/
+```
+
+Lab 1 uses a three-system virtual network:
+
+```text
+client  --------  router  --------  server
+```
+
+The router provides DNS for the MiniCorp web service, and the server provides a simple HTTP service.
+
+Lab 1 intentionally keeps the application simple. Students investigate name resolution, routing, and neighbor information from the client's point of view.
