I've got quite a bit of hands-on experience installing and setting up website programs and utilities - built my own seedbox with rtorrent - but I have to admit defeat with Mediadrop.
There are two issues - the steps themselves, and the written instructions. The installation steps are too cryptic and, at times, unclear. A picture is worth a thousand words - so why not provide screenshots?
"Copy the data folder from your MediaDrop source code next to the production.ini file.", and "Now open http://localhost:8080/ to see how it works! You can try access the admin at http://localhost:8080/admin/". I'm at my browser, and scratch my head as to what I'm doing opening a localhost URL. It obviously means something to a programmer, but not to me. Even 'above' or 'below' /var/www puzzles me - what is your reference point?
What is really needed is a proper installation script, not a list of piecemeal instructions.
I do appreciate the work that's gone into the project, and for making it open source. For this, my thanks! But the installation is beyond me, and - judging by the topics in this forum - a good number of other people.
