How to Clone the Git Repository
The Apache NuttX project uses Git SCM as its version control system.
There are two primary repositories:
- nuttx - The real time operating system itself.
- apps - Optional applications and example programs for the operating system. You can use this repository or make your own custom one.
The main "Single Source of Truth" repositories are hosted by the ASF:
These are synchronized with repositories hosted at GitHub:
How to Contact the Community
The main forum for project communication, to ask a question, get involved, or contribute to NuttX, is our mailing list, dev@nuttx.apache.org. The list is publicly archived and searchable at https://lists.apache.org/list.html?dev@nuttx.apache.org. For more information, see NuttX Community.
Enthusiastic Contributors Welcome!
NuttX is a free open-source project. If you'd like to participate, whether it's to enhance documentation (even these release notes) or dive into the nitty gritty of some low-level drivers, please join us! You can join the conversation at our dev mailing list by emailing dev-subscribe@nuttx.apache.org. The mailing list is open to the public and archived.
