      ``` { .shell }

      ```
    
      I’m using `nano` here mostly because it’s simpler than any other editor on Linux.
    
      You can use any other text editor you wish, provided it saves files as PLAIN TEXT.  `vi`, `emacs`, etc.

      ``` { .shell }
      nano config/config.yml
      ```
    
      I’m using `nano` here simply because it’s built into OSX.  You can use any other text editor you wish, provided it saves files as PLAIN TEXT.  BBedit, TextMate, VSCode, etc.
    
      A common mistake is using TextEdit.app, which saves files as RTF by default.

      [type this into your terminal]

      ``` { .shell }
      notepad .\config\config.yml
      ```
      I’m using `notepad` here simply because it’s built into Windows.  You can use any other text editor you wish, provided it saves files as PLAIN TEXT.
    
From here on in, when this walkthrough says "open the config file", I mean this `nano` or `notepad` command.

??? info ":fontawesome-brands-linux: What if I see an error?"

    If you see something like:
    ``` { .shell .no-copy }
    $ nano config/config.yml
    zsh: command not found: nano
    ```
    You need to switch to another editor like `vi` or `emacs`, or install `nano`, which you would do with `sudo apt install nano`
