+# Contributing to Conway's Game of Life in TypeScript
+
+One of the aims of this project is to learn how best to implement a simple application in various languages which touches on the subject of variables, data structures, program flow and test- or behaviour-driven development.
+
+With that in mind, potential contributors are encouraged to make suggestions on how to improve this repository to get it more in line with community guidelines or convention within the TypeScript programming community, and to make better use of the languages features.
+
+If you do make any changes, however, please ensure that the tests are still passing before you make a pull request.
+
+Thank you!

+# Conways's Game of Life in TypeScript
+
+This is an implementation of [Conway's Game of Life](http://en.wikipedia.org/wiki/Conway's_Game_of_Life) in TypeScript created as an exercise in test-driven TypeScript development. Created by [@basicallydan](https://github.com/basicallydan).
+
+## The Game
+
+Check out the game of life in your terminal by running `npm start`.
+
+## Tests
+
+Jest tests are in `src`, so you just need to run `npm test` to run them.
+
+## Contributing
+
+If you'd like to contribute, that's great and I encourage it - I do, however, also encourage reading the [contributing doc](https://github.com/conwaysgame/typescript/blob/master/contributing.md) first. The golden rule for contributing is that **you ensure that the tests are still passing before you make a pull request.**
+
+## Installation issues
+
+* Using `yarn` to install `ts-jest` seems to cause problems when compiling native parts of the module. Use `npm install -D ts-jest` instead.
