+## Thin caller: build this module's pkgdown site and publish it with GitHub Pages.
+## The job lives in PredictiveEcology/actions, so its setup and pins move once:
+## https://github.com/PredictiveEcology/actions/blob/main/.github/workflows/pkgdown-module.yaml
+## Background: PredictiveEcology/SpaDES-modules#40.
+##
+## Publishes from `development` (the pilot's choice; which branch should publish
+## is an open question on #40). Pull requests build the site without deploying.
+## The site is at https://predictiveecology.github.io/fireSense_SpreadPredict/ until a
+## custom domain is set with the `url` input.
