+# 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 pop-count.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.

+# Eliud's Eggs
+
+Welcome to Eliud's Eggs on Exercism's WebAssembly Track.
+If you need help running the tests or submitting your code, check out `HELP.md`.
+
+## Introduction
+
+Your friend Eliud inherited a farm from her grandma Tigist.
+Her granny was an inventor and had a tendency to build things in an overly complicated manner.
+The chicken coop has a digital display showing an encoded number representing the positions of all eggs that could be picked up.
+
+Eliud is asking you to write a program that shows the actual number of eggs in the coop.
+
+The position information encoding is calculated as follows:
+
+1. Scan the potential egg-laying spots and mark down a `1` for an existing egg or a `0` for an empty spot.
+2. Convert the number from binary to decimal.
+3. Show the result on the display.
+
+Example 1:
+
+```text
+Chicken Coop:
+ _ _ _ _ _ _ _
+|E| |E|E| | |E|
+
+Resulting Binary:
+ 1 0 1 1 0 0 1
+
+Decimal number on the display:
+89
+
+Actual eggs in the coop:
+4
+```
+
+Example 2:
+
+```text
+Chicken Coop:
+ _ _ _ _ _ _ _ _
+| | | |E| | | | |
+
+Resulting Binary:
+ 0 0 0 1 0 0 0 0
+
+Decimal number on the display:
+16
+
+Actual eggs in the coop:
+1
+```
+
+## Instructions
+
+Your task is to count the number of 1 bits in the binary representation of a number.
+
+## Restrictions
+
+Keep your hands off that bit-count functionality provided by your standard library!
+Solve this one yourself using other basic tools instead.
+
+## Reserved Addresses
+
+No linear memory is required for this exercise.
