+### Description
+
+This patch adds `spawninfo` function that is very similar to `spawn`, except it
+also passes some information about the focused client via stdin.
+
+The info is passed in this format:
+
+    PID
+    TITLE
+    APPID
+    TAGS
+    X,Y WIDTHxHEIGHT
+
+I use it for 2 things: grabbing a screenshot of a focused window and adjusting
+volume of audio produced by a focused window (so much simpler than having to
+open pulsemixer every time). If you want to have the same functionality, you
+need to put these scripts into your PATH and make them executable:
+
+[screenshotwin](/dwl/dwl-patches/raw/branch/main/patches/spawninfo/screenshotwin)
+for taking a screenshot (`grim` is required):
+
+```c
+	{ MODKEY|WLR_MODIFIER_SHIFT, XKB_KEY_S,          spawninfo,      SHCMD("screenshotwin") },
+```
+
+[pamixerc](/dwl/dwl-patches/raw/branch/main/patches/spawninfo/pamixerc)
+for adjusting volume (`pactl` is required):
+
+```c
+	{ MODKEY,                    XKB_KEY_XF86AudioRaiseVolume,spawninfo,SHCMD("pamixerc -- -i 5") },
+	{ MODKEY,                    XKB_KEY_XF86AudioLowerVolume,spawninfo,SHCMD("pamixerc -- -d 5") },
+	{ MODKEY,                    XKB_KEY_XF86AudioMute, spawninfo,    SHCMD("pamixerc -- -t") },
+```
