@npalm, it looks like you are either the creator of or strong contributor to the multi-runner module. I'm trying to use it (creatively, to get multiple linux64 runners with distinct extra_labels for different machine types), and am trying to infer the correct arguments to pass the module. Since the examples don't provide an example of the top-level main.tf calling the module, there is no pattern to follow.
I'm using config files under the templates folder, and don't know what to pass as 'multi_runner_config'.
I need to get at least one additional machine type (with a distinct label) to add to our GitHub Actions options, and if the multi-runner approach takes too much longer I'll have to resort to adding another GitHub App for this purpose... not the ideal, but it would get the job done.
I hope you can provide this info without much delay... and perhaps consider adding a sample snippet of how to call the module from main.tf to the README.md and/or the examples code.
