 # PKGBUILD Update Integrity
 
-This repository contains a simple helper script, `update-integrity`. Its
-purpose is to easily update the `sha256` sums in PKGBUILD files. This is
-helpful if you're maintaining a PKGBUILD and have bumped a version or
-updated some sources. It simply replaces the existing hashes with the
-output of `makepkg -g`, first prompting the user for a review and
-confirmation. It requires `kakoune` since we use `kak -f` to perform the
-replacement.
