+# 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
