+.SH NAME
+scrcpy \- Display and control your Android device
+
+
+.SH SYNOPSIS
+.B scrcpy
+.RI [ options ]
+
+
+.SH DESCRIPTION
+.B scrcpy
+provides display and control of Android devices connected on USB (or over TCP/IP). It does not require any root access.
+
+
+.SH OPTIONS
+
+.TP
+.B \-\-always\-on\-top
+Make scrcpy window always on top (above other windows).
+
+.TP
+.BI "\-b, \-\-bit\-rate " value
+Encode the video at the given bit\-rate, expressed in bits/s. Unit suffixes are supported: '\fBK\fR' (x1000) and '\fBM\fR' (x1000000).
+
+Default is 8000000.
+
+.TP
+.BI \-\-crop " width\fR:\fIheight\fR:\fIx\fR:\fIy
+Crop the device screen on the server.
+
+The values are expressed in the device natural orientation (typically, portrait for a phone, landscape for a tablet). Any
+.B \-\-max\-size
+value is computed on the cropped size.
+
+.TP
+.B \-f, \-\-fullscreen
+Start in fullscreen.
+
+.TP
+.B \-h, \-\-help
+Print this help.
+
+.TP
+.BI \-\-max\-fps " value
+Limit the framerate of screen capture (only supported on devices with Android >= 10).
+
+.TP
+.BI "\-m, \-\-max\-size " value
+Limit both the width and height of the video to \fIvalue\fR. The other dimension is computed so that the device aspect\-ratio is preserved.
+
+Default is 0 (unlimited).
+
+.TP
+.B \-n, \-\-no\-control
+Disable device control (mirror the device in read\-only).
+
+.TP
+.B \-N, \-\-no\-display
+Do not display device (only when screen recording is enabled).
+
+.TP
+.BI "\-p, \-\-port " port
+Set the TCP port the client listens on.
+
+Default is 27183.
+
+.TP
+.B \-\-prefer\-text
+Inject alpha characters and space as text events instead of key events.
+
+This avoids issues when combining multiple keys to enter special characters,
+but breaks the expected behavior of alpha keys in games (typically WASD).
+
+.TP
+.BI "\-\-push\-target " path
+Set the target directory for pushing files to the device by drag & drop. It is passed as\-is to "adb push".
+
+Default is "/sdcard/".
+
+.TP
+.BI "\-r, \-\-record " file
+Record screen to
+.IR file .
+
+The format is determined by the
+.B \-\-record\-format
+option if set, or by the file extension (.mp4 or .mkv).
+
+.TP
+.BI \-\-record\-format " format
+Force recording format (either mp4 or mkv).
+
+.TP
+.B \-\-render\-expired\-frames
+By default, to minimize latency, scrcpy always renders the last available decoded frame, and drops any previous ones. This flag forces to render all frames, at a cost of a possible increased latency.
+
+.TP
+.BI "\-s, \-\-serial " number
+The device serial number. Mandatory only if several devices are connected to adb.
+
+.TP
+.B \-S, \-\-turn\-screen\-off
+Turn the device screen off immediately.
+
+.TP
+.B \-t, \-\-show\-touches
+Enable "show touches" on start, disable on quit.
+
+It only shows physical touches (not clicks from scrcpy).
+
+.TP
+.B \-v, \-\-version
+Print the version of scrcpy.
+
+.TP
+.B \-\-window\-borderless
+Disable window decorations (display borderless window).
+
+.TP
+.BI \-\-window\-title " text
+Set a custom window title.
+
+.TP
+.BI \-\-window\-x " value
+Set the initial window horizontal position.
+
+Default is -1 (automatic).\n
+
+.TP
+.BI \-\-window\-y " value
+Set the initial window vertical position.
+
+Default is -1 (automatic).\n
+
+.TP
+.BI \-\-window\-width " value
+Set the initial window width.
+
+Default is 0 (automatic).\n
+
+.TP
+.BI \-\-window\-height " value
+Set the initial window height.
+
+Default is 0 (automatic).\n
