Limit a users access in vsftp to the home directory

I have the following setup:

(1) raspberry pi 3 with Raspbian and vsftp.

The goal is to be able to connect to the ftp raspberry with clients such as WinSCP or Filezilla.

It is possible right now but the user is allowed to see other directories and download from everything. Only upload is limited to his home directory.

This is what I tried so far:

• creating a dedicated ftp user with

  adduser ftpuser --home /home/ftpuser/

• editing the config of vsftp in /etc/vsftp.conf see here (justpaste.it)

So how do I go about this from here?
