+xresources with signal reloading
+================================
+
+Description
+-----------
+This patch adds the ability to configure st via Xresources and signal
reloading.
+This patch is not based on [xresources
patch](https://st.suckless.org/patches/xresources) and is extended from [xst's
commit on
github](https://github.com/gnotclub/xst/commit/c0ffcfbaf8af25468103dd92e0c7e83555e08c7a).
+
+You can basically pass a `USR1` signal to all st processes after updating your
Xresources to reload the settings:
+```
+pidof st | xargs kill -s USR1
+```
+
+Download
