-## some convenience
-there is currently no way to use the `$env` configuration from inside a plugin...
-`nu_plugin_explore` thus uses a CLI argument to do that, i.e. you can pass a config record as the
-first positional argument to the `nu_plugin_explore` command!
-
-however, doing this by hand each time is not the right way to go with that, so let's find another way.
-
-in order to avoid having to pass this record everytime we call `explore`, let's define an alias
-> **Note**  
-> this will not have an impact on the CLI interface of `explore` because it does not have any other
-> option or argument than `config: record` as the first positional argument.
-
-```nushell
-alias nu_plugin_explore = nu_plugin_explore ($env.nu_plugin_explore_config? | default {})
-```
-
-now, you can just call `nu_plugin_explore` and have your config loaded automatically!
-and you can change `$env.nu_plugin_explore_config` as much as you like :partying_face:
-
-> **Note**  
-> if you omit one of the config field of the configuration for `explore`, it's not an issue at all,
-> it will just take the default value instead!
