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:
