What is the gitbook URL for imapfwdoc ?

[chris001]

Hi @nicolas33 !
I'm trying to enable the URL https://imapfwdoc.offlineimap.org
For this, I need the public gitbook URL of these docs.
I found this URL https://www.gitbook.com/book/offlineimap/imapfw-documentation/details it fails to show docs, it redirects to login.
And https://imapfwdoc.gitbook.io is also 404 not found.
What's the public gitbook URL for imapfwdoc ?
