 The [End to end (e2e) testing workflow](https://github.com/informalsystems/ibc-rs/actions?query=workflow%3A%22End+to+End+testing%22) spins up two `gaia` chains (`ibc-0` and `ibc-1`) in Docker containers and one container that runs the relayer. There's a script that configures the relayer (e.g. configure light clients and add keys) and runs transactions and queries. A successful run of this script ensures that the relayer is working properly with two chains that support `IBC`.
 
+### Testing Ethermint-based networks
+At this moment, the automated E2E workflow does not spin up a network with the (post-Stargate) Ethermint module. In the meantime, you can test it manually by following one of the resources below:
+
+- [the official documentation on ethermint.dev](https://ethermint.dev/quickstart/run_node.html)
+- [using the tweaked E2E scripts from the Injective's fork](https://github.com/InjectiveLabs/ibc-rs/commit/669535617a6e45be9916387e292d45a77e7d23d2)
+- [using the nix-based integration test scripts in the Cronos project](https://github.com/crypto-org-chain/cronos#quitck-start)
+
 ### Running an End to end (e2e) test locally
 
 If you want to run the end to end test locally, you will need [Docker](https://www.docker.com/) installed on your machine.
