the ' Getting Started With TDW ' markdown file missing

[robin-bird-go]

Hello, I am a student who want to participate in this tdw challenge, but I am now stuck in TDW building( or maybe using ).

what I've done

1. I have already installed tdw(1.8.7) and magnebot(1.1.1) as the instruction of your markdown file
2. I can successfully run the demo python code

from tdw.controller import Controller
c = Controller()
print("Hello world!")
c.communicate({"$type": "terminate"})

but when it comes to using 'tdw.add_ons' , my tdw doesn't provide this 'add_ons', and I don't know where to use tdw, I think it's because I missed some important 'README' files, would you please tell me or supplement the Getting Started With TDW file?

thank you~:D
