+#A quick guide to contribute to the project:
+
+##Installing the dev environment
+
+1.  Fork the repo
+2.  Clone the repo to local
+3.  Install dependencies: `composer install` (this assumes you have 'composer' aliased to whereever your composer.phar lives)
+4.  Run the tests. We only take pull requests with passing tests, and it's great to know that you have a clean slate:
+    `./bin/phpspec run --format=pretty`
+
+##The actual contribution
+
+1.  Make the changes/additions to the code, committing often and making clear what you've done
+2.  Make sure you write tests for your code, located in the folder structure `spec/Coduo/PHPHumanizer/...`
+3.  Run your tests (often and while coding): `./bin/phpspec run --format=pretty`
+
+##Coding Standards
+
+Try use similar coding standards to what you see in the project to keep things clear to the contributors. If you're unsure, it's always a safe bet to fall-back to the PSR standards.
