 ## Apache NuttX
 
-NuttX is a real-time operating system (RTOS) with an emphasis on standards
-compliance and small footprint. Scalable from 8-bit to 64-bit microcontroller
-environments, the primary governing standards in NuttX are POSIX and ANSI
-standards. Additional standard APIs from Unix and other common RTOS's (such as
-VxWorks) are adopted for functionality not available under these standards, or
-for functionality that is not appropriate for deeply-embedded environments (such
-as fork()).
