How to install?

I know this is a dumb question, but I can't find the answer anywhere on google. How do I install this? I have poetry and python installed, I downloaded the file, extracted it to C:\Users\My_Name\ and I ran poetry install. It just returns this:
` RuntimeError Poetry could not find a pyproject.toml file in C:\Users\blais or its parents at .poetry\lib\poetry\_vendor\py3.9\poetry\core\factory.py:369 in locate 365│ if poetry_file.exists(): 366│ return poetry_file 367│ 368│ else: → 369│ raise RuntimeError( 370│ "Poetry could not find a pyproject.toml file in {} or its parents".format( 371│ cwd 372│ ) 373│ ) `

What am I doing wrong? How am I supposed to install this?
