 ### Tests
 
 The following test groups are included in this repository:
-1. Transport Interface Test validates the implementation of transport interface. The implementation can be plain text or TLS. See [transport interface tests](/src/transport_interface) for details.
-2. PKCS11 Test validates the implementation of PKCS11 interface required by [corePKCS11](https://docs.aws.amazon.com/freertos/latest/portingguide/afr-porting-pkcs.html).

 ### Getting Started
-As a starting point, you should have a working FreeRTOS project and [Unity](https://github.com/ThrowTheSwitch/Unity) ported.
+#### Prerequisites
+1. The tests are ran as an individual test task. You should have a working FreeRTOS project to add test task on.
+2. Unity Test Framework is used to run the tests. See [Unity](https://github.com/ThrowTheSwitch/Unity) for integration guide.
+
+#### Follow these steps to set up the tests
 1. Take FreeRTOS-Libraries-Integration-Tests as a submodule in your project.
 2. Copy config_template/test_execution_config_template.h and config_template/test_param_config_template.h to a project location in the build path, and rename them to test_execution_config.h and test_param_config.h.
 3. Include relevant files into the build system. If using CMake, qualification_test.cmake and corresponding test cmake files in `src/` can be used to include relevant files.
 4. Implement platform functions in [src/common/platform_function.h](https://github.com/FreeRTOS/FreeRTOS-Libraries-Integration-Tests/blob/main/src/common/platform_function.h).
 5. Implement test specific configurations. This is usually in the form of implementing a parameter setup function, which should fill out the struct of parameters passed into the function. Please refer to the documentation of specific tests.
 6. In your application, call `RunQualificationTest()` function to start qualification tests.
 
-For running the tests on your own:
+#### For running the tests locally using your IDE
 1. In test_param_config.h, fill out the parameters required by the test.
 2. In test_execution_config.h, set `<TEST_NAME>_TEST_ENABLED` to 1.
+3. Compile and run the test application in your development environment.
 
+#### For running the tests using AWS IoT Device Tester for Device Qualification 
+See [AWS Qualification Program for FreeRTOS](https://docs.aws.amazon.com/freertos/latest/qualificationguide/afr-qualification.html) for details.
