# Adjust if your main script has a different name or is in a subdirectory.

# If your bot script is e.g. telegram_ytdlp_bot.py, use:

# Expose a volume for downloads (but good for persisting data)
# The bot script currently uses "video_downloads/" relative to its execution path.
# So, /app/video_downloads/ will be the path inside the container.

# Define environment variables for configuration (these will be set at runtime)
# You can set defaults here, but it's better to pass them during `docker run`

# Replace bot.py with the actual name of your main Python script
