 ### Structure
 
-mbed-os has a folder called TEST_APPS that contains everything related to Icetea testing.
+Mbed OS has a folder called `TEST_APPS` that contains everything related to Icetea testing.
 There are currently 3 folders:
 
-- device - contains all the different test applications you can flash to your board
-- icetea-plugins - contains plugins that are being used by some of the testcases, needed for the test execution
-- testcases - contains Icetea testcases written in Python
+- `device` - contains all the different test applications you can flash to your board
+- `icetea_plugins` - contains plugins that are being used by some of the testcases, needed for the test execution

+The testcases depend on test applications.
 
 ### 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.

 ### Running the tests

+Now that the interface has been selected 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`
+`mbed test -m <target> -t <toolchain> --icetea`
 
-This command will compile the mbed-os, then compiles the test applications, creates a test suite and then starts running the tests.

-If you want only to run some specific tests, you can use the -n -option. You can list multiple tests by separating them by comma (,).
+If you only want to run some specific tests, you can use the `-n` option. You can choose multiple tests by separating them with a comma (`,`):

+`mbed test -m <target> -t <toolchain> --icetea -n test1,test2`

-Some devices may offer multiple network interfaces to operate with. For example, UBLOX_EVK_ODIN_W2 offers ethernet and Wi-Fi capabilities.

 The tests can be run for either one of those using already existing test-config -files.

-`>mbed test -m UBLOX_EVK_ODIN_W2 -t <toolchain> --icetea --test-config tools/test_configs/HeapBlockDeviceAndWifiInterface.json`

 #### Providing Wi-Fi access point information
 
-If you are using Wi-Fi interface for running the tests, you need to provide also information about the used access point.
