Vacation plugin and rcd1.3.5

[Franck]

Hello,
I'd like to use vacation plugin on my rcd 1.3.5 and if possible with postfix and the virtual/sql driver beacause it seems to be the most advanced.
Although explanations https://github.com/rplessl/roundcube-vacation-plugin#virtualsql-driver i don't really understand what to do.
Please can you help me ? Maybe a tuto exists

Thank you very much and regards
