 The point of this is to emphasize the verification process that can be completed even without SGX, by reproducing the MRENCLAVE and inspecting remote attestation quotes.
 
-## Replicating the MRENCLAVE build (no SGX required)
+## Init the git submodules
+
+This repo references mtcs as a submodule, but the Dockerfile simply copies mtcs from the current directory.
+So don't forget to have git apply the submodules when cloning the repo
+```bash
+git submodule update --init --recursive
+```
+## Replicating the MRENCLAVE build (no SGX required
 
 The following will build mtcs, then freeze all dependencies from the docker environment into the gramine manifest, and finally display the resulting MRENCLAVE
 ```bash
 docker build . --tag mtcs
-docker run -it -v ./data:/workdir/data mtcs
+docker run mtcs
 ```
 
 Let's see how long this remains reproducible:
