+# Luos Technology
+## The most for the developer​
+Luos provides a simple way to think your hardware products as a group of independant features. You can easily manage and share your hardware products' features with your team, external developers, or with the community. Luos is an open-source lightweight library that can be used on any MCU, leading to free and fast multi-electronic-boards products development. Choosing Luos to design a product will help you to develop, debug, validate, monitor, and manage it from the cloud.
+
+## The most for the community​
+Most of the embedded developments are made from scratch. By using Luos, you will be able to capitalize on the development you, your company, or the Luos community already did. The re-usability of features encapsulated in Luos services will fasten the time your products reach the market and reassure the robustness and the universality of your applications.

+
+## Good practices with Luos​
+Luos proposes organized and effective development practices, guaranteeing development flexibility and evolutivity of your hardware product, from the idea to the maintenance of the industrialized product fleet.
+
+## Let's do this​
+

+# LED strip project example :bulb:
+This project demonstrate how to make and use a simple LED strip through Luos. Feel free to use electronics and code example as you want.
+
+## How to compile the code :computer:
+
+ 1. Download and install [Platformio](https://platformio.org/platformio-ide)
+ 2. Open this folder into Platformio
+ 3. Build (Platformio will do the rest)
+
+## How to open the electronic design :electric_plug:
+You can open [a working example electronic design](https://github.com/Luos-io/luos_engine/tree/main/examples/hardware) with Kicad. This design use Luos_components library for more information to install and use it read [our doc](https://www.luos.io/docs/luos-technology).
+
+## Linked driver
+This project is linked to the [Led strip driver](../../Drivers/led_strip).
+
+## Don't hesitate to read [our documentation](https://www.luos.io/docs/luos-technology), or to post your questions/issues on the [Luos' community](https://discord.gg/luos). :books:
