+*bindgesture* [--exact] [--input-device=<device>] [--no-warn] \
+<gesture>[:<fingers>][:directions] <command>
+	Binds _gesture_ to execute the sway command _command_ when detected.
+	Currently supports the _hold_, _pinch_ or _swipe_ gesture. Optionally
+	can be limited to bind to a certain number of _fingers_ or, for a
+	_pinch_ or _swipe_ gesture, to certain _directions_.
+
+[[ *type*
+:[ *fingers*
+:< *direction*
+|  hold
+:- 1 - 5
+:  none
+|  swipe
+:  3 - 5
+:  up, down, left, right
+|  pinch
+:  2 - 5
+:  all above + inward, outward, clockwise, counterclockwise
+
+	The _fingers_ can be limited to any sensible number or left empty to accept
+	any finger counts.
+	Valid directions are _up_, _down_, _left_ and _right_, as well as _inward_,
+	_outward_, _clockwise_, _counterclockwise_ for the _pinch_ gesture.
+	Multiple directions can be combined by a plus.
+
+	If a _input-device_ is given, the binding will only be executed for
+	that input device and will be executed instead of any binding that is
+	generic to all devices. By default, if you overwrite a binding,
+	swaynag will give you a warning. To silence this, use the _--no-warn_ flag.
+
+	The _--exact_ flag can be used to ensure a binding only matches when exactly
+	all specified directions are matched and nothing more. If there is matching
+	binding with _--exact_, it will be preferred.
+
+	The priority for matching bindings is as follows: input device, then
+	exact matches followed by matches with the highest number of matching
+	directions.
+
+	Gestures executed while the pointer is above a bar are not handled by sway.
+	See the respective documentation, e.g. *bindgesture* in *sway-bar*(5).
+
+	Example:
+```
+		# Allow switching between workspaces with left and right swipes
+		bindgesture swipe:right workspace prev
+		bindgesture swipe:left workspace next
+
+		# Allow container movements by pinching them
+		bindgesture pinch:inward+up move up
+		bindgesture pinch:inward+down move down
+		bindgesture pinch:inward+left move left
+		bindgesture pinch:inward+right move right
+
+```
