Do we have concerns about the web side of this?

@buenaflor I assumed that web path behaviour would stay the same and users can also specify a custom path there as the need it. Don't think we can assume web path to be correct in relation to a custom build path users provide, no?

yeah, was just wondering if it makes sense to call that out somehow but not sure, maybe not?

@buenaflor I changed the naming to match the other parameter and added some context in the readme
