+# Help
+
+## Running the tests
+
+Leiningen can be used to run the exercise's test by running the following command from the exercise's directory:
+
+```bash
+lein test
+```
+
+## REPL
+
+To use the REPL to run the exercise's test, run the following command from the exercise's directory:
+
+```bash
+$ lein repl
+```
+
+Then `require` the exercise's test namespace and the Clojure test namespace):
+
+```clojure
+;; replace <exercise> with the exercise's name
+=> (require '<exercise>-test)
+```
+
+Then call `run-tests` on `<exercise>-test`:
+
+```clojure
+;; replace <exercise> with the exercise's name
+=> (clojure.test/run-tests '<exercise>-test)
+```
+
+## Submitting your solution
+
+You can submit your solution using the `exercism submit src/hello_world.clj` command.
+This command will upload your solution to the Exercism website and print the solution page's URL.
+
+It's possible to submit an incomplete solution which allows you to:
+
+- See how others have completed the exercise
+- Request help from a mentor
+
+## Need to get help?

+# Hello World
+
+Welcome to Hello World on Exercism's Clojure Track.
+If you need help running the tests or submitting your code, check out `HELP.md`.
+
+## Instructions
+
+The classical introductory exercise. Just say "Hello, World!".
+
+["Hello, World!"](http://en.wikipedia.org/wiki/%22Hello,_world!%22_program) is
+the traditional first program for beginning programming in a new language
+or environment.
+
+The objectives are simple:
+
+- Write a function that returns the string "Hello, World!".
+- Run the test suite and make sure that it succeeds.
+- Submit your solution and check it at the website.
+
+If everything goes well, you will be ready to fetch your first real exercise.
+
+## Project Structure
+
+Clojure exercises in exercism use [leiningen](http://leiningen.org/) to configure and run your code
+and use [leiningen standard directory structure](https://github.com/technomancy/leiningen/blob/master/doc/TUTORIAL.md#directory-layout).
+
+You will find a test file named `hello_world_test.clj` inside `test` directory.
+Write your code in `src/hello_world.clj`. It should use the namespace `hello-world` so that tests can pick it up.
+
+## Running tests
+
+Run the tests using `lein test` command and make them pass:
+
+```
+$ lein test
+
+lein test hello-world-test
+
+Ran 3 tests containing 3 assertions.
+0 failures, 0 errors.
+```
+
+Then submit the exercise using:
+
+```
+$ exercism submit src/hello_world.clj
+```
+
+For more detailed instructions and learning resources refer [exercism's clojure language page](http://exercism.io/languages/clojure).

+# Two Fer
+
+Welcome to Two Fer on Exercism's Clojure Track.
+If you need help running the tests or submitting your code, check out `HELP.md`.
+
+## Instructions
+
+`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 name, one for me.
+```
+
+Where "name" 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.
