The example file factorial.md does not work

I tried to run the example code `factorial.md` available at

https://github.com/deephbz/entangled-vscode/blob/main/example/factorial.md

but when I try to run it, I get the error: 

```
can't open file 'Path\\factorial.py': [Errno 2] No such file or directory
```

Also I find the instructions on how to use the extension to be very unclear. It may be a good idea to have a clear working example.
