How to Build a Microservice?

How relevant do you think it is for me, like an MLH net to learn about these things, like how to build microservices? That's an interesting question, because usually I consider microservice as a very low level issue. But if you start breaking down your code, clean code architecture into classes, then when you are shipping this code, software engineers can understand the structure and they can say, okay, this is a service. And then your flow into production is more smooth.
