Thread:Extension talk:Score/Need installation advice

I was going to install this, but I simply can't figure out how to do it.
 * How do I install LilyPond on my web server? I use a web hotel and a common FTP program, would that work? Would I in that case download the most recent version from http://lilypond.org/download.html, or would you advice that I download another version?
 * Do I have to activate file upload on my wiki?
 * The Extension:OggHandler is obsolete. Do I use it anyway?
