+# This GitHub action can publish assets for release when a tag is created.

+# This uses an action (paultyng/ghaction-import-gpg) that assumes you set your

+# secret. If you would rather own your own GPG handling, please fork this action
+# or use an alternative one for key handling.

+# You will need to pass the `--batch` flag to `gpg` in your signing step 
+# in `goreleaser` to indicate this is being used in a non-interactive mode.
