+## General Information
+
+Allows to perform communication with serial connected devices.
+
+Includes following features:
+* Retrieve latest sensor data(**raw**, **full**, **infrared**, **visible**)
+* Retrieve meta information from the internal board state
+* Modify settings for the light sensor.
+
+## Setup
+
+All setup related operations are processed via **Makefile** placed in the root directory.
+
+In order to build IOC project it's required to execute the following command. It uses **CubeMX CLI** to generate **ELF** upload file:
+```shell
+make build
+```
+
+Built **ELF** file is intended to be used for manual upload via **STM Programmer**.
+
+If **ProtocolBuffers** files need to be regenerated it's required to execute the following command:
+```shell
+make generate
+```
