+# Bin2Dec
+
+Binary is the number system all digital computers are based on. 
+Therefore it's important for developers to understand binary, or base 2, 
+mathematics. The purpose of Bin2Dec is to provide practice and 
+understanding of how binary calculations.
+
+Bin2Dec allows the user to enter strings of up to 8 binary digits, 0's
+and 1's, in any sequence and then displays its decimal equivalent.
+
+This challenge requires that the developer implementing it follow these
+constraints:
+
+- Arrays may not be used contain the binary digits entered by the user
+- Determining the decimal equivalent of a particular binary digit in the
+sequence must be calculated using a single mathematical function, for
+example the natural logarithm. It's up to you to figure out which function
+to use.
+
+## User Stories
+
+-   [ ] User can enter up to 8 binary digits in one input field
+-   [ ] User must be notified if anything other than a 0 or 1 was entered.
+-   [ ] User views the results in a single output field containing the 
+decimal (base 10) equivalent of the the binary number that was entered
+
+## Bonus features
+
+-   [ ] User can enter a variable number of binary digits
