+### Build only a single backend
+
+You can control the backends that are built by setting the `GRPC_BACKENDS` environment variable. For instance, to build only the `llama-cpp` backend only:
+
+```bash
+make GRPC_BACKENDS=backend-assets/grpc/llama-cpp build
+```
+
+By default, all the backends are built.
