+## Coding Guidelines and Development 🛠
 
-- **Ensure you stick to the [WordPress Coding Standards](https://make.wordpress.org/core/handbook/best-practices/coding-standards/php/)**
+WooCommerce core uses NPM and Grunt for build tasks, and Composer for installing packages and dependencies. To get your development environment running we recommend [reading here](https://github.com/woocommerce/woocommerce/wiki/How-to-set-up-WooCommerce-development-environment).
+
+If you are contributing code to the REST API or editor blocks, these are developed in external packages.
+- [WooCommerce REST API package](https://github.com/woocommerce/woocommerce-rest-api)
+- [Blocks](https://github.com/woocommerce/woocommerce-gutenberg-products-block)
+
+When writing code for WooCommerce:
+- **Ensure you follow to the [WordPress Coding Standards](https://make.wordpress.org/core/handbook/best-practices/coding-standards/php/)**
 - Install our pre-commit hook using composer. It'll help with the Coding Standards. To install run `composer install` from the command line within the woocommerce plugin directory.
 - Ensure you use LF line endings in your code editor. Use [EditorConfig](http://editorconfig.org/) if your editor supports it so that indentation, line endings and other settings are auto configured.
 - When committing, reference your issue number (#1234) and include a note about the fix.
-- Ensure that your code is compatible with PHP 5.2+.
-- Push the changes to your fork and submit a pull request on the master branch of the WooCommerce repository. Existing maintenance branches will be maintained by WooCommerce developers.
+- Ensure that your code supports the minimum supported versions of PHP and WordPress; this is shown at the top of the `readme.txt` file.
+- Push the changes to your fork and submit a pull request on the master branch of the WooCommerce repository.
 
-Please **don't** modify the changelog or update the .pot files. These will be maintained by the WooCommerce team.
+Please avoid modifying the change-log directly or updating the .pot files. These will be updated by the WooCommerce team.
