 ### Setting Up Prerequisites
+
 Currently, only Ubuntu 14.04+ is officially supported as primary development environment.
 
 There are several dependencies, that should be installed manually. The following list is required for building:
+
 - `gcc` higher than `4.8.2`
   - native
   - arm-none-eabi

 sudo apt-get install gcc g++ gcc-arm-none-eabi cmake cppcheck vera++
 ```
 
+To make our scripts run correctly, several shell utilities should be available on the system:
+
+- `find`
+- `bc`
+- `awk`
+- `sed`
+- `sha256sum`
+- `wget`
+
 Upon first build, `make` would try to setup prerequisites, required for further development and pre-commit testing:
+
 - STM32F3 and STM32F4 libraries
 
 ```bash
 make prerequisites -j
 ```
+
 It may take time, so go grab some coffee:
 
 ```bash
 Setting up prerequisites... (log file: ./build/prerequisites/prerequisites.log)
 ```
 
 ### Building Debug Version
+
 To build debug version for Linux:
+
 ```bash
 make debug.linux -j
 ```
 
 To build debug version for Linux without LTO (Link Time Optimization):
+
 ```bash
 LTO=OFF make debug.linux -j
 ```
 
 ### Checking Patch
+
 ```bash
 make precommit -j
 ```
+
 If some style guidelines, build or test runs fail during precommit, then this is indicated with a message like this:
+
 ```
 Build failed. See ./build/bin/unittests/make.log for details.
