 ## Configuration Schemas
 
-At this time, each service's configuration is defined as a Go struct in a 
-corresponding `config` package. For instance, `m3aggregator`'s config is 
-in [src/cmd/services/m3aggregator/config/config.go](https://github.com/m3db/m3/blob/master/src/cmd/services/m3aggregator/config/config.go).

-M3 uses [go.uber.org/config](https://godoc.org/go.uber.org/config) to load 
-its configuration. This means that we support environment variable interpolation
-of configs. For example:
