 # How to Play
+- At the beginning of a round, you are assigned a starting
+country and a destination country.
+- Hit "B" to check your assignment and your current path
+at any time.
+- Use the D-pad to navigate the alphabetically organized
+pages of countries.
+- Use "A" to select a country and add it to the path.
+- You need to add the starting country to your path,
+and remember the ending country when you are done.
+- Hit "Y" at any time to see the countries which border
+the most recently added country.
+  - Eg. if you just selected USA, you would get a list
+with Canada and Mexico.
+
