+## Announcement management
+
+An announcement is a _regular Hugo page_ contained under the `announcements`
+section of a locale. This means that we leverage Hugo's builtin handling of page
+dates (future or expired), internationalization, and more, to automatically show
+or hide banners depending on the build date, determine banner ordering, handle
+fall back to English banners, etc.
+
+> Announcements are currently used as banners only. We _might_ eventually
+> support slightly more general announcements as well.
+
+### Creating an announcement
+
+To add a new announcement, create an announcement markdown file under the
+`announcements` folder of your localization using the following command:
+
+```sh
+hugo new --kind announcement content/YOUR-LOCALE/announcements/announcement-file-name.md
+```
+
+Adjust according to your desired locale and file name. Add the announcement text
+as the body of the page.
+
+> For banners, the announcement body should be a short phrase.
+
+{{% alert title="For localizations" %}}
+
+If you are creating a **locale specific announcement override**, make sure that
+you use the **same filename** as the English language announcement.
+
+{{% /alert %}}
+
+### Announcement list
+
+Any given announcement will appear in a site build when the build date falls
+between the `date` and `expiryDate` fields of the announcement. When those
+fields are missing they are assumed to be "now" and "forever", respectively.
+
+Announcements will appear in the standard page order as determined using Hugo's
+[Regular pages](https://gohugo.io/methods/site/regularpages/) function. That is,
+the "lightest" announcements (by `weight`) will appear first; when weights are
+the same or unspecified, the most recent announcements (by `date`) will appear
+first, etc.
+
+So, if you want to force an announcement to the top, use a negative `weight` in
+the front matter.
+
