      This is a baseline challenge. Only one challenge of this kind should exist. System will consider any challenge 
      with base score of 1 to be baseline.

      This challenge exists for the purpose of score scaling. The number of solves on this challenge is used as 
      divisor on solve counts for every other challenge when recomputing scores.

      The flag should usually be listed in the description, like so: `myctf{I_can_copypaste}`.

      Difficulty should be a value of 0-6, where 0 is None, 1 is Very Easy, 5 is Very Hard, and 6 is Ultra Nightmare.

      Descriptions use Markdown to style the contents.

      For challenge settings, flags: 1 enables client-side facilities to access hidden challenges. Scoring can have 
      one of the following values: static (no score decay), jeopardy (score decay), firstcomefirstserve (score decay 
      with solve freeze). Currently only jeopardy is implemented.

    hints:

        Challenges can also specify connectable endpoints. Endpoint type can have one the following values:

        - 0: unknown type, formatted as `host:port`
        - 1: netcat, formatted as `nc host port`
        - 2: http, formatted as `http://host:port/` unless port is 80, then `http://host/`
        - 3: ssh, formatted as `ssh host -p port` unless port is 22, then `ssh host`; note that value of `host` is not 
          validated, so it's possible to specify user@host as value
        - 4: ssl, formatted as `openssl s_client -connect host:port` unless port is 443, then 
          `openssl s_client -connect host`
        - 5: https, formatted as `https://host:port/` unless port is 443, then `https://host/`

    endpoint:
      type: 1
      host: tcp.myrosettactfinstance.xyz
