+### Setting up an environment to run the WPUnit tests
+
+1. Create a `.env` file from the provided `.env.testing` and update the following section.
+
+    ```env
+    # WordPress database configurations
+    DB_NAME=wordpress
+    DB_HOST=app_db
+    DB_PORT=3306
+    DB_USER=wordpress
+    DB_PASSWORD=password
+    ROOT_PASSWORD=password
+    WP_TABLE_PREFIX=wp_
+    SKIP_DB_CREATE=true
+    SKIP_WP_SETUP=true
+
+    ```
+
+    The variable should be point to a local instance of MySQL and `SKIP_DB_CREATE` and `SKIP_WP_SETUP` should be set to `false`.
+2. Run `composer installTestEnv` from the terminal in the plugin root directory. This will run the setup script and install all the required dependencies.
+3. Run the tests by running `vendor/bin/codecept run wpunit` from the root directory. To learn about the libraries used to write the tests see [Codeception](https://codeception.com/), [WPBrowser](https://wpbrowser.wptestkit.dev/modules/WPBrowser/), and [WPGraphQL TestCase](https://github.com/wp-graphql/wp-graphql-testcase)
+
+### Setting up a Docker environment to run the E2E tests
+
+1. Run `composer installTestEnv` from the terminal in the plugin root directory to install all the required dependencies.
+2. Next run `composer dRunApp`. This will build and start the docker network at http://localhost:8080 based off the configuration found in the `docker-compose.yml` in the project root.
+3. Last run the test by running `composer dRunTest`. This runs the test suite by utilizing the `docker exec` command to run `vendor/bin/codecept run` from the project root within the docker container for wordpress site. You can pass further parameter to this comment by using the `FILTER` environment variable like so `FILTER="acceptance NewCustomerCheckingOutCept --debug" composer dRunTest`.
+
+> **NOTE:** If you have no interest in the generated docker environment outside of automated test you can simply the process by just running the `dRunTestStandalone` command after the `installTestEnv` command combining steps 2 & 3, `composer dRunTestStandalone`. The command also reads the `FILTER` variables as well to so filter is possible `FILTER="acceptance NewCustomerCheckingOutCept --debug" composer dRunTestStandalone`.
