# Installation

An easy to use and portable C++ library, pre-configured to work with **hundreds of development boards**.

The library implements a streaming connection protocol (i.e. the device stays always connected to the cloud), that allows for a **low latency, bi-directional** communication. 

Use [Quickstart flow](https://docs.blynk.io/en/getting-started/what-do-i-need-to-blynk) for a quick demo and make sure to explore [Blynk Library documentation](https://docs.blynk.io/en/blynk-library-firmware-api/configuration) afterwards.
