as simple as editing a yaml file! set your key as the bot command and set its corresponding value to send to the user whenever user sent the command.

a list of key/value pair. key as the command and the message as the answerer. you can have a list of each photos, audios, documents, videos.

commands:
    - key: foo
      message: bar
      photos:
        - "path/2/1.jpg"
        - "assets/2.jpg"

    - key: foo2
      message: bar2
      audios:
        - "assets/audio.ogg"
      photos:
        - "assets/1.jpg"
      documents:
        - "assets/1.pdf"
      videos:
        - "assets/1.mp4"

    - key: hi
      message: hi there, how are you?

• set API_KEY for bot token
• python3 -m venv .env
• source .env/bin/activate
• ./main.py

docker version is in the way so don't worry, you will just need to simply set the API_KEY, thats all.
