+#
+# Package Maintenance instructions:
+# 1. The ebuild is in the form of intel-microcode-<INTEL_SNAPSHOT>_p<COLLECTION_SNAPSHOT>.ebuild
+# 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 can go in your devspace, add the URL to SRC_URI if it's not there
+# https://dev.gentoo.org/~<dev nick>/dist/intel-microcode/intel-microcode-collection-${COLLECTION_SNAPSHOT}.tar.xz
+#
+# PV:
+# * the first date is upstream
+# * the second date is snapshot (use last commit date in repo) from intel-microcode-collection
