 ### Preparing your work environment
 
-#### Prerequisities
+#### Prerequisites
 
-You need Icetea and mbed-cli that supports Icetea, installed.
+You need Icetea and version 1.8.0 or higher of Mbed CLI installed.
 
 #### Selecting the network interface to use
 
-Depending on a device, there might be a default network interface type defined in the mbed-os/targets/targets.json, which is used to locate a test-config file by default. 
-If there is not, or you want to use a different interface than the default, you need to provide a relevant test-config -file to the mbed test with --test-config option.
-The test-config file contains the necessary information for the test application, there are some test-config files located under mbed-os/tools/test_configs.
-Devices which have their network drivers residing inside mbed-os can use generic test_configs like HeapBlockDeviceAndEthernetInterface.json and HeapBlockDeviceAndWifiInterface.json. Otherwise you need to use a device specific test-config.

+Now that you have selected the interface, you can run the Icetea tests from the `mbed-os` root on your command-line by running the following command:
+
+`mbed test -m <target> -t <toolchain> --icetea`
