        Hello, brave adventurer!
        Welcome to Linux Odyssey, an adventure filled with terminal magic!
        Think of the terminal as your magic wand. You control the computer with **text spells**, a useful skill for any aspiring programmer!
        The area below is your stage for casting spells: the terminal. Ready to cast your first one?
        Enter `echo hello` below, then press Enter to see what happens!

  - id: echo-hello
    name: Enter `echo hello` in the terminal
    requirements:
      - start
    condition:
      command: ^echo hello$

        Congratulations on running your first command!
        You should see this in the terminal:
        ```
        commander:~ $ echo hello
        hello
        ```
        The prompt `commander:~ $` means the computer is waiting for a command.
        After you enter `echo hello`, the computer prints "hello" on the next line.

        A command is like a sentence telling the computer what to do.
        Take `echo hello`, for example:
        - `echo` tells the computer to print something
        - `hello` is the text to print
        So when you enter `echo hello`, the computer prints "hello".

        Now try making the terminal display the text `next`.
        If you get stuck, click the `Hint` button for help.

        Enter `echo next` to continue to the next step.

  - id: echo-next
    name: Enter `echo next` in the terminal
    requirements:
      - echo-hello
    condition:
      command: ^echo next$

        Congratulations! You now know how to use `echo`.
        You might wonder why we need a command like this.
        Although `echo` is simple, printing text is a basic building block for many tasks.
        In this adventure, we will also use `echo` to trigger events.
        That is all for this quest. Enter `echo finish` to complete it.
