Ok, where/how do I get a Template Provider? I assume this is referencing a block template? Is that yet another special software stack I need to run just to solo mine from my own node?

So far I have:

An ASIC with Brains, waiting to be pointed to a pool.

Stratum (https://github.com/stratum-mining/stratum) for running the Pool and Tranlator (part that the miners talk to, I think).

Now I need to understand wtf a Template Provider is....
