+         This option allows you to choose the algorithm which will be used to
+         compress modules when 'make modules_install' is run. (or, you can
+         choose to not compress modules at all.)
 
-         Compresses kernel modules when 'make modules_install' is run; gzip or
-         xz depending on "Compression algorithm" below.
+         External modules will also be compressed in the same way during the
+         installation.
 
-         module-init-tools MAY support gzip, and kmod MAY support gzip and xz.
+         For modules inside an initrd or initramfs, it's more efficient to
+         compress the whole initrd or initramfs instead.
 
-         Out-of-tree kernel modules installed using Kbuild will also be
-         compressed upon installation.
+         This is fully compatible with signed modules.
 
-         Note: for modules inside an initrd or initramfs, it's more efficient
-         to compress the whole initrd or initramfs instead.
+         Please note that the tool used to load modules needs to support the
+         corresponding algorithm. module-init-tools MAY support gzip, and kmod
+         MAY support gzip and xz.
 
-         Note: This is fully compatible with signed modules.
+         Your build system needs to provide the appropriate compression tool
+         to compress the modules.
 
-         If in doubt, say N.
+         If in doubt, select 'None'.
