+### Description
+
+This patch adds an ability to add or change client rules at runtime.
+
+Sometimes it happens that some client rule I've set is not relevant in the
+current circumstance and adds major disturbance and annoyance to my work
+(e.g., `isfloating` is set or unset and I want the opposite). Changing the rule
+is not an option because it will require recompilation and restarting dwl, which
+is even worse. Having an option of always being able to change a rule solves
+this issue.
+
+The patch only adds one keybinding (`Alt+Shift+R`) to toggle `isfloating`
+option. Upon pressing it, dwl will try to find a matching rule for the focused
+client and change its `isfloating` setting. If there's no such a rule, a new
+rule will be added. The new rule will inherit an appid of the focused client.
+
+It's very easy to add support for more rule options from other patches as well.
+You just need to define a new function similar to `setruleisfloating` and add a
+new keybinding to `config.h`. For example, this is a function I created for my
+build to toggle `noswallow` option from the [swallow][swallow] patch:
+
+```c
+void
+setrulenoswallow(const Arg *arg)
+{
+	Rule *r = getrule(focustop(selmon));
+	if (!r)
+		return;
+	r->noswallow = !r->noswallow;
+}
+```
+
+You can also try [menurule][menurule] patch if you want to be able to edit rules
+with dmenu.
