+# 2. The INTEL_SNAPSHOT upstream is located at: https://github.com/intel/Intel-Linux-Processor-Microcode-Data-Files
+# 3. The COLLECTION_SNAPSHOT is created manually using the following steps:
+#   a. Clone the repository https://github.com/platomav/CPUMicrocodes
+#   b. Rename the Intel directory to intel-microcode-collection-<YYYYMMDD>
+#   c. From the CPUMicrocodes directory tar and xz compress the contents of intel-microcode-collection-<YYYYMMDD>:
+#      tar -cJf intel-microcode-collection-<YYYYMMDD>.tar.xz intel-microcode-collection-<YYYYMMDD>/
+#   d. This file should be signed and uploaded to masterkup.  For detailed instructions, please go to: https://wiki.gentoo.org/wiki/Project:Infrastructure/Project_Distfiles
+#   e. The SRC_URI will then be of the form:
