+# The current version code scheme for the package apk is:
+#      Mbbbba
+# where
+#    M - Chromium milestone number minus 36. (1 or more digits). This is to
+#        ensure that our version codes are lower than the ones currently used by
+#        Chrome for Android, so that we can adopt their scheme in future.
+# bbbb - manually specified build number (exactly 4 digits). This defaults to
+#        0000, or 9999 in local builds.
+#    a - device architecture (exactly 1 digit). Current valid values are:
+#           1 : armv7-a
+#           2 : armv8-a (arm64)
+#           4 : mips
+#           7 : x86
+#           8 : x86_64
+#        64-bit architectures must be higher than their corresponding 32-bit
+#        architectures to ensure that 64-bit devices receive the multiarch APK.
+#        x86 must be higher than ARM to avoid x86 devices receiving ARM APKs
+#        and running them in emulation.
+
+# TODO(torne): get this from Chromium automatically.
