+.SH DESCRIPTION
+.B lisgd
+(or libinput **synthetic** gesture daemon) lets you bind gestures based on
+libinput touch events to run specific commands to execute. For example,
+dragging left to right with one finger could execute a particular command
+like launching a terminal. Directional L-R, R-L, U-D, and D-U gestures and
+diagnoal LD-RU, RD-LU, UR-DL, UL-DR gestures are supported with 1 through 
+n fingers.
+
+Unlike other libinput gesture daemons, lisgd uses touch events to
+recognize synthetic swipe gestures rather than using the libinput's
+gesture events. The advantage of this is that the synthetic gestures
+you define via lisgd can be used on touchscreens, which normal libinput
+gestures don't support.
+
+This program was built for use on the Pinephone however it could be used in 
+general for any device that supports touch events, like laptop touchscreens 
+or similar. You may want to adjust the threshold depending on the device 
+you're using.

+.BR \-d ", " \-d\ devicepath\fR
+Path of the dev filesystem device to monitor (like /dev/input/event1).
+
+.TP
+.BR \-t ", " \-t\ distancethreshold\fR
+Threshold in libinput units (pixels) after which a gesture registers. Defaults
+to 300.
+
+.TP
+.BR \-r ", " \-r\ degreesofleniency\fR
+Number of degrees offset each 45-degree interval may still be recognized within.
+Maximum value is 45. Default value is 15. E.g. U-D is a 180 degree gesture
+but with 15 degrees of leniency will be recognized between 165-195 degrees.

+Number of milliseconds gestures must be performed within to be registered. After

+
+.TP
+.BR \-v \fR
+Enables verbose mode which prints debugging messages.
+
+.TP
+.BR \-g ", " \-g\ nfingers,gesture,command\fR
+Allow you to bind a gesture wherein nfingers is an integer, gesture is 
+one of {LR,RL,DU,UD,DLUR,URDL,ULDR,DLUR}, and the shell command to be executed.
+
+The -g option can be used multiple times to bind multiple gestures.
