 Next is an example `rootCmd` function from the `simapp` application. It instantiates the root command, adds a [_persistent_ flag](#flags) and `PreRun` function to be run before every execution, and adds all of the necessary subcommands.

+`rootCmd` has a function called `initAppConfig()` which is useful for setting the application's custom configs.
+By default app uses Tendermint app config template from SDK, which can be over-written via `initAppConfig()`.
