 Here are the common reported problems and their status.
 
 
-### On Windows, my device is not detected
+## `adb` issues
 
-The most common is your device not being detected by `adb`, or is unauthorized.
+`scrcpy` execute `adb` commands to initialize the connection with the device. If
-Check everything is ok by calling:
+`adb` fails, then scrcpy will not work.
 
-    adb devices
+In that case, it will print this error:
 
-Windows may need some [drivers] to detect your device.
+>     ERROR: "adb push" returned with value 1
+
+This is typically not a bug in _scrcpy_, but a problem in your environment.
+
+To find out the cause, execute:
+
+```bash
+adb devices
+```
+
+### `adb` not found
+
+You need `adb` accessible from your `PATH`.
+
+On Windows, the current directory is in your `PATH`, and `adb.exe` is included
+in the release, so it should work out-of-the-box.
+
+
+### Device unauthorized
+
+Check [stackoverflow][device-unauthorized].
+
+[device-unauthorized]: https://stackoverflow.com/questions/23081263/adb-android-device-unauthorized
+
+
+### Device not detected
+
+If your device is not detected, you may need some [drivers] (on Windows).

-### I can only mirror, I cannot interact with the device
+### Several devices connected
+
+If several devices are connected, you will encounter this error:
+
+>     adb: error: failed to get feature set: more than one device/emulator
+
+the identifier of the device you want to mirror must be provided:
+
+```bash
+scrcpy -s 01234567890abcdef
+```
+
+Note that if your device is connected over TCP/IP, you'll get this message:
+
+>     adb: error: more than one device/emulator
+>     ERROR: "adb reverse" returned with value 1
+>     WARN: 'adb reverse' failed, fallback to 'adb forward'
+
+This is expected (due to a bug on old Android versions, see [#5]), but in that
+case, scrcpy fallbacks to a different method, which should work.

+
+
+### Conflicts between adb versions
+
+>     adb server version (41) doesn't match this client (39); killing...
+
+This error occurs when you use several `adb` versions simultaneously. You must
+find the program using a different `adb` version, and use the same `adb` version
+everywhere.
+
+You could overwrite the `adb` binary in the other program, or ask _scrcpy_ to
+use a specific `adb` binary, by setting the `ADB` environment variable:
+
+```bash
+set ADB=/path/to/your/adb
+scrcpy
+```
+
+
+### Device disconnected
+
+If _scrcpy_ stops itself with the warning "Device disconnected", then the
+`adb` connection has been closed.
+
+Try with another USB cable or plug it into another USB port. See [#281] and
+[#283].
