+# Help
+
+## Running the tests
+
+## Setup
+
+Go through the setup [instructions for WebAssembly][docs-exercism-wasm] to install the necessary dependencies.
+
+## Requirements
+
+Install assignment dependencies:
+
+```shell
+# Using npm
+npm install
+
+# Alternatively using yarn
+yarn
+```
+
+## Making the test suite pass
+
+All exercises come with a test suite to help you validate your solution before submitting.
+You can execute these tests by opening a command prompt in the exercise's directory, and then running:
+
+```bash
+# Using npm
+npm test
+
+# Alternatively using yarn
+yarn test
+```
+
+In some test suites all tests but the first have been skipped.
+
+Once you get a test passing, you can enable the next one by changing `xtest` to `test`.
+
+## Writing custom tests
+
+If you wish to write additional, custom, tests, create a new file `custom.spec.js`, and submit it with your solution together with the new file:
+
+```shell
+exercism submit numbers.wat custom.spec.js
+```
+
+[docs-exercism-wasm]: https://exercism.org/docs/tracks/wasm/installation
+
+## Submitting your solution
+
+You can submit your solution using the `exercism submit two-fer.wat` 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?
+
+If you'd like help solving the exercise, check the following pages:
+
+- The [WebAssembly track's documentation](https://exercism.org/docs/tracks/wasm)
+- The [WebAssembly track's programming category on the forum](https://forum.exercism.org/c/programming/wasm)
+- [Exercism's programming category on the forum](https://forum.exercism.org/c/programming/5)
+- The [Frequently Asked Questions](https://exercism.org/docs/using/faqs)
+
+Should those resources not suffice, you could submit your (incomplete) solution to request mentoring.
+
+To get help if you're having trouble, you can use one of the following resources:
+
+- [/r/WebAssembly](https://www.reddit.com/r/WebAssembly/) is the WebAssembly subreddit.
+- [Github issue tracker](https://github.com/exercism/wasm/issues) is where we track our development and maintenance of Javascript exercises in exercism. But if none of the above links help you, feel free to post an issue here.

+# Two Fer
+
+Welcome to Two Fer on Exercism's WebAssembly Track.
+If you need help running the tests or submitting your code, check out `HELP.md`.
+
+## Introduction
+
+In some English accents, when you say "two for" quickly, it sounds like "two fer".
+Two-for-one is a way of saying that if you buy one, you also get one for free.
+So the phrase "two-fer" often implies a two-for-one offer.
+
+Imagine a bakery that has a holiday offer where you can buy two cookies for the price of one ("two-fer one!").
+You go for the offer and (very generously) decide to give the extra cookie to a friend.
+
+## Instructions
+
+Your task is to determine what you will say as you give away the extra cookie.
+
+If your friend likes cookies, and is named Do-yun, then you will say:
+
+```text
+One for Do-yun, one for me.
+```
+
+If your friend doesn't like cookies, you give the cookie to the next person in line at the bakery.
+Since you don't know their name, you will say _you_ instead.
+
+```text
+One for you, one for me.
+```
+
+Here are some examples:
+
+|Name    |Dialogue
+|:-------|:------------------
+|Alice   |One for Alice, one for me.
+|Bohdan  |One for Bohdan, one for me.
+|        |One for you, one for me.
+|Zaphod  |One for Zaphod, one for me.
