Trying to create a project with the sources in a remote host

I have the sources of a web app in a remote server. Now I'm trying to create a project in NB from this remote project a开发者_JS百科nd work in remote (the files are saved in the remote host).

So I chose "New PHP Application from remote server", and a form appears with a field called "Sources folder". But...what is that exactly?? I have the sources in the remote host. So..what should I write there?

NB 6.9.1
