 ## Further reading
 The config format for the JSON files are adapted from the [example-configs](https://github.com/cosmos/relayer/tree/main/docs/example-configs)
 in the relayer repo. Our configs will get out of date very quickly: the preview chain id changes
 on every merge into main, for instance. Short-term, that's fine: we want to exercise IBC
 in our CI deployments, and dynamically generating the configs is good enough. Longer term, we'll want
 to upload our configs to the [chain-registry repo](https://github.com/cosmos/chain-registry).
+Full documentation on the underlying steps used by the relayer can be found in the
+[cross-chain docs](https://github.com/cosmos/relayer/blob/main/docs/create-path-across-chain.md).
