+## @file  PrmPkg.dec
+# This package provides support for the Platform Runtime Mechanism (PRM).
+#
+# The following key elements of PRM are maintained in this package:
+#
+# 1. PRM interfaces - Comprised of interfaces shared with the operating system such as ACPI table structures
+#                     in addition to internal firmware interfaces such as protocols and library interfaces.
+#
+# 2. PRM generic drivers - EDK II drivers that implement generic functionality such that a platform can quickly
+#                          and reliably adopt PRM.
+#
+# 3. PRM module - An independently updatable PE/COFF binary that conforms to the unique requirements of a PRM module.
+#                 PRM modules expose functions for operating system invocation referred to as PRM handlers.
+#
+# 4. PRM handler - A function in a PRM module. The function is identified through PRM interfaces in the OS by a GUID.
