Known Issues

Forbidden characters in name on windows (resolved, with side effect)

On windows, there are some characters are forbidden in a file or directory name, so I replaced them into + character.

Following characters will be replaced into + character: /, \, ?, %, *, :, |, ", <, >.

What me need to do next?

Hello. Can you explain me, what me need to do?
I downloaded nodejs and Yarn as you said. But I cant understand what me need to do now. The page says: 1. Copy .env.example to .env and configure it well. What means by ".env"? I created a folder with the same name in "nodejs" folder, where Node.exe located. But i running Node.exe, and nothing happens! Can you explain, what me need to do, to download images from Fantia? I`m a little bit noob in Programming Languages, and actually know only Python.
