Just an idea:
probably it would be a good idea to describe the configuration parameters for the EthTxManager in some separate doc and reference it from there. The same would go for the Etherman (because it is nested in the EthTxManager). WDYT?

Maybe make sense to set the defaults values and mention that is taking advantage of the common vars like: L1URL, L2URL,....

Will do the same in a separate PR

I have pointed out to default.go file which contains all the default values
