I can create one soon. Leave everything at the default values when setting up the docker container. Use binhex's version. When you add a folder to share start the path with /media/"share/etc" (the quoted part is the path to whatever folder.
You can find the path by going into the shares tab and browsing to where you want to go. Right click the folder name at the top of this page and it will show you the path starting with /mnt. Use /media instead like the above example and it should work okay.
I will still try to create a short tutorial video this week sometime and share the link here.
