Here's a short story:

The competition is open to any eligible club down to Levels 10 of the English football league system - all 92 professional clubs in the Premier League and Football League (Levels 1 to 4), and several hundred "non-league" teams in Steps 1 to 6 of the National League System (Levels 5 to 10). A record 763 clubs competed in 2011–12. The tournament consists of 12 randomly drawn rounds followed by the semi-finals and the final. Entrants are not seeded, although a system of byes based on league level ensures higher ranked teams enter in later rounds - the minimum number of games needed to win the competition ranges from six to fourteen. 

The first six rounds are the Qualifying Competition, from which 32 teams progress to the first round of the Competition Proper, meeting the first of the 92 professional teams. The last entrants are the Premier League and Championship clubs, into the draw for the Third Round Proper. In the modern era, non-league teams have never reached the quarter finals, and teams below Level 2 have never reached the final.[note 1] As a result, as well as who wins, significant focus is given to those "minnows" (smaller teams) who progress furthest, especially if they achieve an unlikely "giant-killing" victory.
