I need to manually install the pgfornament package into my 2015 TexLive installation, on Mac OS X (Snow Leopard, a very old version of the Mac OS). It's the first time that I want to manually install something for LaTeX, so I feel very uneasy and don't want to mess my installation. Of course, I've consulted the package documentation:
but it seems to be inconsistent in the installation section (especially on page 5). I've downloaded and unzipped the package, which gives a folder called pgfornament. I opened my 2015 TexLive folder (called "2015"), and I don't see any "/texmf/tex/latex" folder in there, as requested in the package documentation.
So what should I do now?

EDIT: I've found a solution there:
