+# String Calculator Kata
+
+From: http://osherove.com/tdd-kata-1/ 
+
+1. Create a simple String calculator with a method int Add(string numbers).
+   1. The method can take 0, 1 or 2 numbers, and will return their sum (for an empty
+      string it will return 0). For example "" or "1" or "1,2"
+   2. Start with the simplest test case of an empty string and move to 1 and
+      two numbers
+   3. Remember to solve things as simply as possible so that you force yourself
+      to write tests you did not think about
+   4. Remember to refactor after each passing test
+2. Allow the Add method to handle an unknown amount of numbers
+3. Allow the Add method to handle new lines between numbers (instead of commas).
+   1. the following input is ok:  "1\n2,3"  (will equal 6)
+   2. the following input is NOT ok:  "1,\n" (not need to prove it - just
+      clarifying)
+4. Support different delimiters. 
+   1. To change a delimiter, the beginning of the string will contain a
+      separate line that looks like this: `//[delimiter]\n[numbers...]`, for
+      example `//;\n1;2` should return three where the default delimiter is `;`
+      .
+   2. the first line is optional. all existing scenarios should still be
+      supported
+5. Calling Add with a negative number will throw an exception "negatives not
+   allowed" - and the negative that was passed.if there are multiple negatives,
+   show all of them in the exception message
+6. Numbers bigger than 1000 should be ignored, so adding 2 + 1001  = 2
+7. Delimiters can be of any length with the following format:  `//[delimiter]\n`
+   for example: `//[***]\n1***2***3` should return 6
+8. Allow multiple delimiters like this:  `//[delim1][delim2]\n` for example
+   `//[*][%]\n1*2%3` should return 6.
+9. make sure you can also handle multiple delimiters with length longer than one
+   char
