+# Instructions
+
+Tally the results of a small football competition.
+
+Based on an input file containing which team played against which and what the outcome was, create a file with a table like this:
+
+```text
+Team                           | MP |  W |  D |  L |  P
+Devastating Donkeys            |  3 |  2 |  1 |  0 |  7
+Allegoric Alaskans             |  3 |  2 |  0 |  1 |  6
+Blithering Badgers             |  3 |  1 |  0 |  2 |  3
+Courageous Californians        |  3 |  0 |  1 |  2 |  1
+```
+
+What do those abbreviations mean?
+
+- MP: Matches Played
+- W: Matches Won
+- D: Matches Drawn (Tied)
+- L: Matches Lost
+- P: Points
+
+A win earns a team 3 points.
+A draw earns 1.
+A loss earns 0.
+
+The outcome is ordered by points, descending.
+In case of a tie, teams are ordered alphabetically.
+
+## Input
+
+Your tallying program will receive input that looks like:
+
+```text
+Allegoric Alaskans;Blithering Badgers;win
+Devastating Donkeys;Courageous Californians;draw
+Devastating Donkeys;Allegoric Alaskans;win
+Courageous Californians;Blithering Badgers;loss
+Blithering Badgers;Devastating Donkeys;loss
+Allegoric Alaskans;Courageous Californians;win
+```
+
+The result of the match refers to the first team listed.
+So this line:
+
+```text
+Allegoric Alaskans;Blithering Badgers;win
+```
+
+means that the Allegoric Alaskans beat the Blithering Badgers.
+
+This line:
+
+```text
+Courageous Californians;Blithering Badgers;loss
+```
+
+means that the Blithering Badgers beat the Courageous Californians.
+
+And this line:
+
+```text
+Devastating Donkeys;Courageous Californians;draw
+```
+
+means that the Devastating Donkeys and Courageous Californians tied.
