+# RISC-V Profiles and Platform Specification
+
+The files in this project are used to create the RISC-V Profiles and
+Platform Specification.  This specification defines the set of firmware
+and hardware required of a RISC-V platform so that it may install
+and run various operating systems.
+
+The content of the specification is created and controlled by the RISC-V
+Profiles and Platform Specification Technical Subcommittee.  Information
+about the subcommittee can be found at
+https://lists.riscv.org/g/tech-unixplatformspec.
+Please note that membership in RISC-V International is required to post
+to the mailing list, but it is publicly readable.  Membership in RISC-V
+International is free for individual community members.
+
+All discussion of this specification occurs on the task group mailing
+list.  Please use github issues for bug reports.
