+* =org-keynote=
+
+This is the most minimal presentation mode I could write to simulate a
+keynote from an org-mode document.
+
+** Configuration
+
+There are two hooks you could take advantage of.
+Typical doom-emacs configuration:
+
+#+BEGIN_SRC elisp
+(use-package! org-keynote
+  :config
+  (add-hook 'org-keynote-mode-hook
+            (lambda ()
+              (org-sticky-header-mode -1)
+              (doom/increase-font-size 3)
+              (org-display-inline-images)))
+
+  (add-hook 'org-keynote-mode-quit-hook
+            (lambda ()
+              (org-sticky-header-mode -1)
+              (doom/reset-font-size)
+              (org-remove-inline-images)))
+  (map! :map org-keynote-mode-map
+        :ni "<right>" #'org-keynote-next
+        :ni "<left>" #'org-keynote-prev
+        :ni "q" #'org-keynote-quit'))
+#+END_SRC
