 By default your notes live in ~/notes, but you can change that to anywhere you like by setting the `$NOTES_DIRECTORY` environmental variable. See [how do I configure this?](#how-do-i-configure-this) for more details.

You'll typically want to set these as environment variables in your `.bashrc`, `.zshrc`, or similar.

Remember to use `export` command when setting environment variables on the command line in Linux.
 
-There are also more complex options available. You can set any configuration properties either in the environment, or in a config file (stored in `~/.config/notes/config`), with settings in config overriding those in your environment. This allows you to configure a different `$EDITOR` for notes to everything else, if you like. The config file is a good choice for more complex set ups, but probably not worth worrying about to start with. We've included an example config in this repo for you ([config.example](config.example)) that you can copy if you like.
