-==========
-
-Description
------------
-This patch is actually a xresources patch for dwm, applied to dmenu.
-
-The patch add the ability to configure dmenu via Xresources by using arbitrary
-resources, not specific ones. Xresources values override default settings and can be
-overriden by command line arguments.
-
-All thanks should go to the authors of xresources patch for dwm, xresources and
-xrdb patches for st.

-xresources
-==========
-
-Description
------------
-This patch was originally made by Michał Lemke has been slightly modified to
-work with dmenu 4.9.
-
-This patch adds the ability to configure dmenu via Xresources. At startup,
-dmenu will read and apply the change to the applicable resource. Below are the
-resources that can be changed and what they change:
-
-- dmenu.font : font or font set
-- dmenu.background : normal background color
-- dmenu.foreground : normal foreground color
-- dmenu.selbackground : selected background color
-- dmenu.selforeground : selected foreground color
-
-Note: Values in Xresources will override values in config.h, but will be
-overridden by command line arguments.

+# xresources
+
+Runtime configuration using X Resources.
+
+## Description
+
+This patch adds Xresources support to dmenu. At startup, dmenu reads the
+relevant X resources and applies them at runtime. A declarative array defines
+the resources, making the patch easy to extend with more settings.
+dmenu recognizes the following resources by default:
+
+- `dmenu.font`: font or font set
+- `dmenu.prompt`: prompt string
+- `dmenu.background`: normal background color
+- `dmenu.foreground`: normal foreground color
+- `dmenu.backgroundSel`: selected background color
+- `dmenu.foregroundSel`: selected foreground color
+- `dmenu.backgroundOut`: output background color
+- `dmenu.foregroundOut`: output foreground color
+- `dmenu.topbar`: position of dmenu at top (1) or bottom (0)
+- `dmenu.lines`: number of lines for vertical display
+
+Values set in Xresources override those in config.h. Command line
+arguments take precedence over both.
