+# How to setup configuration folder for FSFW
+
+It is recommended to copy the content of the defaultcfg folder
+into a config folder which is in the same directory as the Flight
+Software Framework submodule. After that, the config.mk folder should be
+included by the primary Makefile with CURRENTPATH set correctly.

 ### Instructions
 
+To run the fsfw unittests in the project, perform following steps:
+
+1. Copy the testcfg folder  the project root (folder containing the FSFW).
+2. There is a makefile inside the testcfg folder which can be used to have 
+   a starting point to compile the unit tests. Copy that Makefile to the project
+   root
+3. Create a folder named catch2 (can have other name which requires Makefile 
+   adaption) and copy the Catch2 header files there (NOTE: CMake support
+   not enabled yet!)
+   
 ### Eclipse CDT settings
 
 The default eclipse terminal has issues displaying the colors used
