 _Scrcpy_ uses `adb` to communicate with the device, and `adb` can [connect] to a

+device over TCP/IP. The device must be connected on the same network as the
+computer.
+
+##### Automatic
+
+An option `--tcpip` allows to configure the connection automatically. There are
+two variants.
+
+If the device (accessible at 192.168.1.1 in this example) already listens on a
+port (typically 5555) for incoming adb connections, then run:
+
+```bash
+scrcpy --tcpip=192.168.1.1       # default port is 5555
+scrcpy --tcpip=192.168.1.1:5555
+```
+
+If adb TCP/IP mode is disabled on the device (or if you don't know the IP
+address), connect the device over USB, then run:
+
+```bash
+scrcpy --tcpip    # without arguments
+```
+
+It will automatically find the device IP address, enable TCP/IP mode, then
+connect to the device before starting.
+
+##### Manual
+
+Alternatively, it is possible to enable the TCP/IP connection manually using
+`adb`:

 1. Connect the device to the same Wi-Fi as your computer.

-#### SSH tunnel
+#### Tunnels

 To connect to a remote device, it is possible to connect a local `adb` client to
 a remote `adb` server (provided they use the same version of the _adb_
 protocol).

+##### Remote ADB server
+
+To connect to a remote ADB server, make the server listen on all interfaces:
+
+```bash
+adb kill-server
+adb -a nodaemon server start
+# keep this open
+```
+
+**Warning: all communications between clients and ADB server are unencrypted.**
+
+Suppose that this server is accessible at 192.168.1.2. Then, from another
+terminal, run scrcpy:
+
+```bash
+export ADB_SERVER_SOCKET=tcp:192.168.1.2:5037
+scrcpy --tunnel-host=192.168.1.2
+```
+
+By default, scrcpy uses the local port used for `adb forward` tunnel
+establishment (typically `27183`, see `--port`). It is also possible to force a
+different tunnel port (it may be useful in more complex situations, when more
+redirections are involved):
+
+```
+scrcpy --tunnel-port=1234
+```
+
+
+##### SSH tunnel
+
+To communicate with a remote ADB server securely, it is preferable to use a SSH
+tunnel.

 [Physical keyboard]: https://github.com/Genymobile/scrcpy/pull/2632#issuecomment-923756915

+#### Physical mouse simulation (HID)
+
+Similarly to the physical keyboard simulation, it is possible to simulate a
+physical mouse. Likewise, it only works if the device is connected by USB, and
+is currently only supported on Linux.
+
+By default, scrcpy uses Android mouse events injection, using absolute
+coordinates. By simulating a physical mouse, a mouse pointer appears on the
+Android device, and relative mouse motion, clicks and scrolls are injected.
+
+To enable this mode:
+
+```bash
+scrcpy --hid-mouse
+scrcpy -M  # short version
+```
+
+You could also add `--forward-all-clicks` to [forward all mouse
+buttons][forward_all_clicks].
+
+[forward_all_clicks]: #right-click-and-middle-click
+
+When this mode is enabled, the computer mouse is "captured" (the mouse pointer
+disappears from the computer and appears on the Android device instead).
+

+/* The representation of input events in scrcpy is very close to the SDL API,
+ * for simplicity.
+ *
+ * This scrcpy input events API is designed to be consumed by input event
+ * processors (sc_key_processor and sc_mouse_processor, see app/src/trait/).
+ *
+ * One major semantic difference between SDL input events and scrcpy input
+ * events is their frame of reference (for mouse and touch events): SDL events
+ * coordinates are expressed in SDL window coordinates (the visible UI), while
+ * scrcpy events are expressed in device frame coordinates.
+ *
+ * In particular, the window may be visually scaled or rotated (with --rotation
+ * or MOD+Left/Right), but this does not impact scrcpy input events (contrary
+ * to SDL input events). This allows to abstract these display details from the
+ * input event processors (and to make them independent from the "screen").
+ *
+ * For many enums below, the values are purposely the same as the SDL
+ * constants (though not all SDL values are represented), so that the
+ * implementation to convert from the SDL version to the scrcpy version is
+ * straightforward.
+ *
+ * In practice, there are 3 levels of input events:
+ *  1. SDL input events (as received from SDL)
+ *  2. scrcpy input events (this API)
+ *  3. the key/mouse processors input events (Android API or HID events)
+ *
+ * An input event is first received (1), then (if accepted) converted to an
+ * scrcpy input event (2), then submitted to the relevant key/mouse processor,
+ * which (if accepted) is converted to an Android event (to be sent to the
+ * server) or to an HID event (to be sent over USB/AOA directly).
