set here an option to run it with corret uid and gid. Otherwise all the generated files ill be owned by root on the host machine.

what about metric server address? Default one is "localhost:9090", to make it accessible from host os you need to set it to ":9090", and for macs you need to additionally map port (-p) in the docker command

By default the metrics are disabled so no need to provide the host.

### Install relayer (with docker)

For the document simplicity we use the alias for the command which will be executed in docker.

is it the doc which we will share with our relayers ?
I think for now it looks a bit unclear where to start and where to stop.
Maybe we should add a separate doc for them with all the steps thy are supposed to do ?

or lets discuss

README.md line 61 at r3 (raw file):

```bash
coreumbridge-xrpl-relayer keys-coreum add coreum-relayer

nit: I that most of our relayers are likely to already have generated mnemonics
Is --recover option supported here ? Shall we mention that they could use existing mnemonic ?

But that's obvios IMO. To have it just for docker is too much.

We will re-write it and move to docs, the dev-rel team will help with it.

This doc desribes the simplies option. But --recover make sense. Updated.

if this is only docker then ok
just devrel in their doc should probably mention it
