### Cosmos (C# Open Source Managed Operating System) [![Build status](https://ci.appveyor.com/api/projects/status/kust7g5dlnykhkaf/branch/master?svg=true)](https://ci.appveyor.com/project/CosmosOS/cosmos/branch/master) [![Join the chat at https://gitter.im/CosmosOS/Cosmos](https://img.shields.io/badge/GITTER-Join%20Chat-brightgreen.svg)](https://gitter.im/CosmosOS/Cosmos?utm_source=badge&utm_medium=badge&utm_campaign=pr-badge&utm_content=badge) [![GitHub release](https://img.shields.io/github/release/CosmosOS/Cosmos.svg)](https://github.com/CosmosOS/Cosmos/releases) Cosmos is an operating system "construction kit", built from the ground up around the IL2CPU compiler in C# and our home-brewed language called X#. It's current stage is only usable for academic work. Some day Cosmos will be ready for production work, but to reach that stage we need more developers. Specifically, we need a few more low-level developers to help the few core developers who are currently overwhelmed with work. Downloads: --------- Cosmos is available in two flavors: * **User Kit** - The User Kit is used to develop your operating system in Visual Studio. If you are new to Cosmos, you can learn [here](https://github.com/CosmosOS/Cosmos/wiki). [Latest Release anvailable](https://github.com/CosmosOS/Cosmos/releases/latest) * **Development Kit** - The Development Kit is the full Cosmos source and build tools. If you need to modify the Cosmos core functions or modify built-in drivers, boot, compiler, etc.. you will need to use Development Kit.
