+** Similar emacs package: speedread
+
+Available in marmalade or [[https://github.com/vapniks/speedread/blob/master/speedread.el][github]] It has several nice features and does
+not align on an accent character. Eventually I'd like to merge the two
+packages.

+** Algorithm details
+
+*** Main algorithm code location
+In =./spray.el=, the functions =spray--word-at-point=, =spray--update= and =spray-start= contain the main algorithm of choosing a word, an accent character and an interval to display it. Word splitting is also duplicated the same way as in those functions throughout ./spray.el.
+
+*** Algorithm translated from code to english
+
+Words are split at space, tab, newline, and emdash characters.
+
+Each word is displayed for (60 / the choosen wpm) seconds, except if the
+word ends with =.!?,;:—= or is greater than 9 characters long, in which
+case it is displayed for twice as long.
+
+When started, an added delay is optionally added, based on the
+spray-ramp variable. See it's documentation for details.
+
+The accent location is chosen as the nth character in a word, depending
+on its length, based on the following table
+| length | accent position |
+| 1 | 1 |
+| 2-5 | 2 |
+| 6-9 | 3 |
+| 10-13 | 4 |
+| 14+ | 5 |
+
** Contributions are welcome!
-There's lots of features and enhancements to do. The algorithm has lots of room for improvement. Also, other projects may have algorithm improvements we can port over to this one.
