+## Allow content preference based on message context
+
+The preference for which sub-part of a multipart/alternative part is shown is
+globally set. For example, if you prefer showing the html version over the text
+based, you can set:
+
+    (setq notmuch-multipart/alternative-discouraged '("text/plain" "text/html"))
+
+However, sometimes you might want to adapt your preference depending on the
+context. You can override the default settings on a per-message basis by
+providing a function that has access to the message and which returns the
+discouraged type list. For example:
+
+    (defun my/determine-discouraged (msg)
+      (let* ((headers (plist-get msg :headers))
+             (from (or (plist-get headers :From) "")))

+
+    (setq notmuch-multipart/alternative-discouraged
+          'my/determine-discouraged)
+
+This would discourage text/html and multipart/related generally, but discourage
+text/plain should the message be sent from whatever@mail.address.com.
