Set up MiminServer on QNAP

[PK4]

Please help! I am trying to set up MiminServer to manage my music Library on my new QNAP TS-133, which I have set up. I have created a music storage folder (with albums) and downloaded Miminserver to the QNAP. But I cannot figure out this next step in Miminserver instructions: "Enter the full path to your content directory in the field below and click Save. To find the correct path to enter, you can use File Station, as shown on this page."
My TS-133 File Station folder does not look anything like the content on "that page", but still, I did attempt to follow those instructions, and added the full path to my content directory and got this message: "Content directory isn't a folder: /share/DataVol1/mymusic"

Is there a video out there that has step-by-step for Miminserver set up on a NAS? Thanks much!
