+# Otherwise, invoke the line editor with the previous notes available
 # as an editor history.  Two quick taps on the return/enter key finish
 # the note, or you can use use ^X^W as usual (ZZ in vicmd mode).
 
+# The application is configured by three zstyles, all using the context
+# ":sticky-note".  The first two styles are "notefile" and "maxnotes"
+# to name the file in which notes are stored and the maximum number of
+# notes to retain:
+#   zstyle :sticky-note notefile ~/.zsticky
+#   zstyle :sticky-note maxnotes 1000
+
+# The "theme" style may be set to control the appearance of the notes.
+# The style is an associative array; the current set of values (defaults
+# in parens) are:
+#   bg    => name or ANSI escape for background color (yellow)
+#   fg    => name or ANSI escape for foreground color (black)
+#   color => ANSI escape for color scheme ($theme[bg]$theme[fg])
+#   reset => ANSI escape to restore "normal" colors
+# Values given as names are looked up in the $bg and $fg arrays from the
+# "colors" function.  If a "color" field is set, the "bg" and "fg" fields
+# are not used.  Example:
+#   zstyle :sticky-note theme \
+#     bg red \
+#     fg $fg_bold[yellow]
+
+# For backwards compatibility with an earlier version, the notefile may
+# also be named by the STICKYFILE variable (defaults to $HOME/.zsticky).
+# The number of notes stored may be given by STICKYSIZE (1000).
+
 # I encourage all you creative people to contribute enhancements ...
-# no-prize for the first person to put the most recent sticky note in
