Location of tex-input files

I’m using Scrivener 3 with MMD6 - I can’t figure out where to put my .tex files…
With MMD6, the syntax for the metadata is ‘latex config -> some-id’, which leads to the files mmd6-some-id-leader, *-begin and *-footer to be inserted into the generated .tex-file.

When compiling via Multimarkdown->PDF, the tex-engine complains about being unable to locate these files.
Where do I have to copy them?

Thanks, Philipp

According to the well hidden readme in the mmd6 latex support files package installer (I used Pacifist to read it, or browse github source):

github.com/fletcher/MultiMarkdo … /README.md

Thank you
