+## Build `esnext` Examples
+
 For each of the examples that include an `esnext` example the following commands are required to build the plugins:
 
 - `npm install` to install the node packages
 - `npm run build` to build the production version of the plugin or `npm run dev` to build a development version of the plugin and watch changes for automatic rebuild
 
+## Local Environment
+
+First, you need a WordPress Environment to run the plugin on. The quickest way to get up and running is to use the provided docker setup. Install [docker-ce](https://store.docker.com/search?type=edition&offering=community) and [docker-compose](https://docs.docker.com/compose/install/) by following the most recent instructions on the docker site.
+
+In the folder of your preference, clone this project and enter the working directory:
+
+```
+git clone git@github.com:WordPress/gutenberg-examples.git
+cd gutenberg-examples 
+```
+
+To bring up this local WordPress instance run:
+
+```
+docker-compose up -d
+```
+
+The WordPress should be available at http://localhost:9999
+
+To stop this local WordPress instance later run:
+
+```
+docker-compose stop
+```
