+;; A simple module to help post things to your tekuti blog. You’ll want to
+;; customize the ‘tekuti-host’ variable to point to your own blog. You should be
+;; asked for your credentials, which should then be stored in ~/.authinfo.gpg.
+
+;; Currently you should add these headers to your org document that you want to
+;; send up:
+
+;; #+TITLE: SOME TITLE
+;; #+DATE: <2021-06-03 Thu 22:45>
+;; #+TAGS: comma,separated
+;; #+COMMENTS: open
+;; #+COMMENTS_DATE:
+;; #+STATUS: publish
+
+;; The main entry point is ‘tekuti-send’. Call this from an org-mode buffer to
+;; export the buffer to HTML and send it up to your blog.
