 ESP8266 modules come in different shapes and forms, but most important difference is which firmware version it is programmed with. To make sure that your module has mbed-os compatible firmware follow update guide: https://developer.mbed.org/teams/ESP8266/wiki/Firmware-Update
 
 ## Testing
-The ESP8266 library contains the core network tests taken from mbed OS. After installing mbed CLI and importing the mbed OS library, the tests can be ran with the `mbed test` command:
+The ESP8266 library contains the core network tests taken from mbed OS. To run the tests you will need mbed CLI and mbed OS.
+
+First, setup the the esp8266-driver and mbed-os repositories for testing:
+``` bash
+# Sets up the ESP8266 for testing
+mbed import esp8266-driver
+cd esp8266-driver
+mbed add mbed-os
+```
+
+Now you should be able to run the network tests with `mbed test`:
 ``` bash
 # Runs the ESP8266 network tests, requires a wifi access point
-mbed test -t <COMPILER HERE> -m <BOARD HERE> -n tests-net* --compile -DMBED_CFG_ESP8266_SSID='"<SSID HERE>"' -DMBED_CFG_ESP8266_PASS='"<PASS HERE>"'
+mbed test -t <COMPILER HERE> -m <BOARD HERE> -n tests-net* --compile -DMBED_CFG_ESP8266_SSID='<SSID HERE>' -DMBED_CFG_ESP8266_PASS='<PASS HERE>'
+mbed test -t <COMPILER HERE> -m <BOARD HERE> -n tests-net* --run --verbose
+```
+
+There are a couple other options that can be used during testing:
+- MBED_CFG_ESP8266_SSID - SSID of the wifi access point to connect to
+- MBED_CFG_ESP8266_SSID - Passphrase of the wifi access point to connect to
+- MBED_CFG_ESP8266_TX - TX pin for the ESP8266 serial connection (defaults to D1)
+- MBED_CFG_ESP8266_RX - TX pin for the ESP8266 serial connection (defaults to D0)
+- MBED_CFG_ESP8266_DEBUG - Enabled debug output from the ESP8266
+
+For example, here is how to enabled the debug output from the ESP8266:
+``` bash
+# Run the ESP8266 network tests with debug output, requires a wifi access point
+mbed test -t <COMPILER HERE> -m <BOARD HERE> -n tests-net* --compile -DMBED_CFG_ESP8266_SSID='<SSID HERE>' -DMBED_CFG_ESP8266_PASS='<PASS HERE>' -DMBED_CFG_ESP8266_DEBUG=true
 mbed test -t <COMPILER HERE> -m <BOARD HERE> -n tests-net* --run --verbose
 ```
