+# Description:
+#   Removes and reloads the psmouse module, which controls PS/2 mice and
+#   touchpads on many Linux systems. This can resolve cases where the
+#   touchpad/mouse has stopped responding.
+#
+# Usage:
+#   ./reload-psmouse.sh
+#
+# Requirements:
+#   - Linux
+#   - sudo privileges
+#   - psmouse kernel module
+#
+# Notes:
+#   Reloading psmouse may temporarily disconnect the touchpad/mouse.
+#   Systems using a different input driver may not be affected.
