+Running integration tests requires you to have relayer docker image present on your machine:
+
+```BASH
+# TODO: upstream these changes
+git clone -b daniyar/custom-entrypoint git@github.com:near/pagoda-relayer-rs-fastauth.git
+docker build pagoda-relayer-rs-fastauth -t pagoda-relayer-rs-fastauth
+```

+
+```BASH
+docker build . -t near/mpc-recovery
+```
+
+**Note**. You will need to re-build the Docker image each time you make a code change and want to run the integration tests.
+
+Finally, run the integration tests:
+
+```BASH
