I want to know the answer to the following question:
Who is the competition open too?
All the background I'm provided with is that "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).". Is that enough to answer the question?
Answer: yes
