How to use external_resource_packs in auto-host.json

[Dementore711]

Hi ,

I am trying to use a resource pack hosted on mc-packs.net (for sound files) along with the auto hosted pack from polymer. I found "external_resource_packs" this setting in auto-host.json. But I am not sure on how it should be filled. Could you please give the syntax for this? (I tried to check the comments in AutoHostConfig.java, but I am not well versed in java)
