+# Two Fer
+
+`Two-fer` or `2-fer` is short for two for one. One for you and one for me.
+
+Given a name, return a string with the message:
+
+```text
+One for X, one for me.
+```
+
+Where X is the given name.
+
+However, if the name is missing, return the string:
+
+```text
+One for you, one for me.
+```
+
+Here are some examples:
+
+|Name    |String to return 
+|:-------|:------------------
+|Alice   |One for Alice, one for me. 
+|Bob     |One for Bob, one for me.
+|        |One for you, one for me.
+|Zaphod  |One for Zaphod, one for me.
+
+## Coding the solution
+
+Look for a stub file having the name two_fer.go
+and place your solution code in that file.
+
+## Running the tests
+
+To run the tests run the command `go test` from within the exercise directory.
+
+If the test suite contains benchmarks, you can run these with the `--bench` and `--benchmem`
+flags:
+
+    go test -v --bench . --benchmem
+
+Keep in mind that each reviewer will run benchmarks on a different machine, with
+different specs, so the results from these benchmark tests may vary.
+
+## Further information
+
+For more detailed information about the Go track, including how to get help if
+you're having trouble, please visit the exercism.io [Go language page](http://exercism.io/languages/go/resources).

+
+## Submitting Incomplete Solutions
+It's possible to submit an incomplete solution so you can see how others have completed the exercise.
