+When company-mode is available (Emacs >= 24), address completion\r
+candidates are shown in a nice popup box. This is triggered either by\r
+pressing TAB or by waiting a while during typing an address. The\r
+completion is based entirely on the asynchronous address harvesting\r
+from notmuch-address.el so the GUI is theoretically not blocked for\r
+long time.\r
+\r
+The completion works similarly as the TAB-initiated completion from\r
+notmuch-address.el, i.e. quick harvest based on user input is executed\r
+first and only after full harvesting is finished, in-memory cached data\r
+is used.\r
