 # Note regarding Google Chrome
 
-Google has a policy of yanking older versions of Google Chrome from their PPA whenever a new major
-version is released.  This means images with non-current chrome versions will fail to build.  Until
-a better solution is worked out, we will remove images based on older Chrome versions from the build
-process, but preserve them for reference within a comment in the `.gitlab-ci.yml` file.
-
-These images will persist in the docker repository for legacy use, but will no longer be recompiled.
-If an update ever needs to be made to an image containing an older version of Chrome, a workaround
-can be modeled after https://gitlab.com/gitlab-org/gitlab-build-images/merge_requests/54
+Google has a policy of yanking older versions of Google Chrome from their PPA
+whenever a new major version is released. To help maintain consistant build
+images, there is a CI step that saves the latest Google Chrome .deb into an S3
+bucket.  The install for Chrome will attempt to retrieve from the bucket if it
+cannot find the file in the apt repository. See `scripts/cache-google-chrome`
+for more details.
