+Zephyr™ Project
+###############
+
+The Zephyr™ Project is a scalable real-time operating system (RTOS) supporting
+multiple hardware architectures, optimized for resource constrained devices,
+and built with security in mind.
+
+The Zephyr OS is based on a small-footprint kernel designed for use on
+resource-constrained systems: from simple embedded environmental sensors and
+LED wearables to sophisticated smart watches and IoT wireless gateways.
+
+The Zephyr kernel supports multiple architectures, including ARM Cortex-M,
+Intel x86, ARC, NIOS II and RISC V, and a large number of
+`supported boards`_.
+
+Community Support
+*****************
+
+The Zephyr Project Developer Community includes developers from member
+organizations and the general community all joining in the development of
+software within the Zephyr Project. Members contribute and discuss ideas,
+submit bugs and bug fixes, and provide training. They also help those in need
+through the community's forums such as mailing lists and IRC channels. Anyone
+can join the developer community and the community is always willing to help
+its members and the User Community to get the most out of the Zephyr Project.
+
+Welcome to the Zephyr community!
+
+Resources
+*********
+
+Here’s a quick summary of resources to find your way around the Zephyr Project
+support systems:
+
+* **Zephyr Project Website**: The https://zephyrproject.org website is the
+  central source of information about the Zephyr Project. On this site, you’ll
+  find background and current information about the project as well as all the
+  relevant links to project material.  For a quick start, refer to the
+  `Zephyr Introduction`_ and `Getting Started Guide`_.
+
+* **Releases**: Source code for Zephyr kernel releases are available at
+  https://zephyrproject.org/downloads. On this page,
+  you'll find release information, and links to download or clone source
+  code from our GitHub repository.  You'll also find links for the Zephyr
+  SDK, a moderated collection of tools and libraries used to develop your
+  applications.
+
+* **Source Code in GitHub**: Zephyr Project source code is maintained on a
+  public GitHub repository at https://github.com/zephyrproject-rtos/zephyr.
+  You'll find information about getting access to the repository and how to
+  contribute to the project in this `Contribution Guide`_ wiki article.
+
+* **Samples Code**: In addition to the kernel source code, there are also
+  many documented `Sample and Demo Code Examples`_ that can help show you
+  how to use Zephyr services and subsystems.
+
+* **Documentation**: Extensive Project technical documentation is developed
+  along with the Zephyr kernel itself, and can be found at
+  https://zephyrproject.org/doc.  Additional documentation is maintained in
+  the `Zephyr GitHub wiki`_.
+
+* **Issue Reporting and Tracking**: Requirements and Issue tracking is done in
+  our JIRA system: https://jira.zephyrproject.org. You can browse through the
+  reported issues and submit issues of your own.
+
+* **Mailing List**: The `Zephyr Mailing Lists`_ are perhaps the most convenient
+  way to track developer discussions and to ask your own support questions to
+  the Zephyr project community.
+  You can also read through message archives to follow
+  past posts and discussions, a good thing to do to discover more about the
+  Zephyr project.
+
+* **IRC Chatting**: You can chat online with the Zephyr project developer
+  community and other users in our IRC channel #zephyrproject on the
+  freenode.net IRC server. You can use the http://webchat.freenode.net web
+  client or use a client-side application such as pidgin.
