+===================================
+Using a ttf font file in Matplotlib
+===================================
+
+Although it is usually not a good idea to explicitly point to a single ttf file
+for a font instance, you can do so using the `font_manager.FontProperties`
+*fname* argument.
+
+Here, we use the Computer Modern roman font (``cmr10``) shipped with
+Matplotlib.
+
+For a more flexible solution, see :doc:`/gallery/api/font_family_rc_sgskip` and
+:doc:`/gallery/text_labels_and_annotations/fonts_demo`.
