Tickets are basically like notices on a noticeboard.
They are used to keep track of what needs done.
Something needs done (added/fixed/etc) then a ticket is made and assigned to whoever.
Over time, files and comments are added, respective to the ticket in question.
Once all done, files are whisked away to a special place and the ticket is closed.
That's quite a few tickets done actually, didn't realise that.
