DamlHub Integrations

Hello everyone!

I noticed on DamlHub the Browse Integration tab. I’d like to try CoinDesk. But I didn’t find materials on how to use it. Am I right, with this thing I can request prices directly from the daml code?
I saw on GitHub the integration has a dar file. Should I use it as a dependency in my project to make it work? Does it work with the latest daml?
I found materials on how I can create my custom integration but don’t see any on how I can use the existing one. What does a development process look like? Can I run the thing locally with Sandbox?

Maybe we have some “generic” integration that I can use as a benchmark for integration setup. I deployed one integration directly on hub, but understood nothing about how to use it :man_facepalming:

Where should I start?

Thanks!
Victor
