+Edit `config.h`
+
+```c
+#include <X11/XF86keysym.h>
+ 
+/* volume keys*/
+static const char *upvol[] = { "/usr/bin/pactl", "set-sink-volume", "0", "+5%", NULL };
+static const char *downvol[] = { "/usr/bin/pactl", "set-sink-volume", "0", "-5%", NULL };
+static const char *mutevol[] = { "/usr/bin/pactl", "set-sink-mute", "0", "toggle", NULL };
+ 
+/* backlight */
+static const char *brightnessup[] = { "sudo", "xbacklight", "-inc"m "5", NULL };
+static const char *brightnessdown[] = { "sudo", "xbacklight", "-dec", "5", NULL };
+```
+
+Append the following lines in `static Key keys[]` array
+```c
+static Key keys[] = {
+    { 0, XF86XK_AudioLowerVolume, spawn, {.v = downvol} },
+    { 0, XF86XK_AudioMute, spawn, {.v = mutevol }},
+    { 0, XF86XK_AudioRaiseVolume, spawn, {.v = upvol} },
+    { 0, XF86XK_MonBrightnessUp, spawn, {.v = brightnessup} },
+    { 0, XF86XK_MonBrightnessDown, spawn, {.v = brightnessdown} },
+};
