+### Build Custom Podman Images
+```bash
+make images
+```
+This will build the following images:
+- `tcp-client`: A simple TCP client that sends a message to a server (this will run in h1-pod)
+- `tcp-server`: A simple TCP server that listens for a message from a client (this will run in all other pods)
+
+You can configure the target IP of the client and the port of the server in the [tcp/Containerfile.server](tcp/Containerfile.server) and [tcp/Containerfile.client](tcp/Containerfile.client) files respectively.
+
+Furthermore, you can specify which image to run in the hosts by changing the `IMG` and `ARGS` variables in [scripts/switch_container/build.sh](scripts/switch_container/build.sh).
