Simple: if you are using v1.5.0 already and have not customized any of the files listed in the changed_files-v1-5-1.html document, then simply replace those files with the new versions contained herein.
If you HAVE customized or altered certain files, simply re-do your customizations in the new version of those particular files by making the same changes needed.
If you are using Addons/Plugins that have made alterations to those files, it is best to compare those changed files against the original v1.5.0 files, and see what changes were there ... and then re-build those changes in the v1.5.1 file.
If you are upgrading from a version OLDER than v1.5.0, then please do a standard complete site upgrade.
For a list of files that have been changed since v1.5.0, see the changed_files-v1-5-1.html
