 - `--listen-address` - the address with port the node would listen to. For example, you can use it to redefine port or to make the exporter accessible from the outside by listening on `127.0.0.1`. Defaults to `:9500` (so it's accessible from the outside on port 9500)
 - `--local-tendermint-rpc` - local Tendermint RPC URL to query node stats. Defaults to `http://localhost:26657`
-- `--remote-tendermint-rpc` - remote Tendermint RPC URL to query node stats. Defaults to `http://rpc.cosmos.network:443`
-- `--binary-path` - path to a fullnode binary to query version from. It may fail if it's located in $GOPATH and the path is relative, so better to explicitly provide the absolute path.
-- `--github-org` - GitHub organization name
-- `--github-repo` - Github repository. This param and `--github-org` are used to specify the repository hosting the full node binary sources.
+- `--remote-tendermint-rpc` - remote Tendermint RPC URL to query node stats. Defaults to `http://rpc.cosmos.network:443`. Optional, if not provided, the exporter won't scrape data from the remote node.
+- `--binary-path` - path to a fullnode binary to query version from. It may fail if it's located in $GOPATH and the path is relative, so better to explicitly provide the absolute path. Optional, if not provided the exporter won't collect data on binary version.
+- `--github-org` - GitHub organization name.

 - `--log-devel` - logger level. Defaults to `info`. You can set it to `debug` to make it more verbose.
