+### Description
+This patch adds per-client keyboard layout and ability to send current
+keyboard layout information to a status bar.
+
+Only per-client feature is enabled by default. You can edit
+`kblayout_file` and `kblayout_cmd` variables to notify a status bar
+about keyboard layout.
+
+[Someblocks](https://sr.ht/~raphi/someblocks) config that works
+with the example settings in `config.h`:
+
+```c
+static const Block blocks[] = {
+	/*Icon*/	/*Command*/		/*Update Interval*/	/*Update Signal*/
+	{"", "cat /tmp/dwl-keymap",					0,		1},
+};
+```
+
+Both of these features are included in one patch because their
+implementation happens to share some code. If you don't need
+any of these features, just disable it in `config.h`.
