How do I onboard my organization as a Trust Anchor?

I would like to onboard my organization to the mainnet in order to issue credentials to our users.

I’ve read all the documentation on Hyperledger Indy, and it seems fairly straightforward. I have been able to run the “indy-dev” example locally and everything works fine.

So how do I do this in real life? How do I onboard the organization I work for as Trust Anchor on the actual mainnet? I can’t seem to find this information referenced anywhere in the documentation.
