+# This GitHub action can publish assets for release when a tag is created.
+# Currently its setup to run on any tag that matches the pattern "v*" (ie. v0.1.0).
+#
+# This uses an action (paultyng/ghaction-import-gpg) that assumes you set your 
+# private key in the `GPG_PRIVATE_KEY` secret and passphrase in the `PASSPHRASE`
+# 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.
