+### GUI
+
+To view logs, click on the `Console` tab. Optionally, change filter from `Information` to `Debug` for more detailed logs.
+
+To export logs, click `Help` -> `Export diagnostics...` in the top menu bar.
+
+Sometimes OpenTabletDriver crashes hard. This is usually caused by a bug in OpenTabletDriver. Due to the crash, it will be impossible to retrieve the logs from GUI. In this case, you can find a partial log in the following locations:
+
+| OS | Location |
+| --- | --- |
+| Windows | `%appdata%\OpenTabletDriver\daemon.log` |
+| Linux | `~/.local/share/OpenTabletDriver/daemon.log` |
+| macOS | `~/Library/Application Support/OpenTabletDriver/daemon.log` |
+
+### Daemon
+
+The output from daemon is the log.
+
+On Linux when running daemon via systemd service, the log for daemon is recorded by systemd. To view the log, run `journalctl --user-unit opentabletdriver.service`.

+
+Make sure that the installed OpenTabletDriver version is at least **0.6.3.0**. If still not working even with the latest version, refer to the instructions below depending on if you installed OpenTabletDriver via:
+
+- [Package manager](#package-manager)
+- [Built from source](#built-from-source)
+
+### Package manager
+
+#### Standard FHS distro
+
+Run the following script in bash as root:
+
+```bash
+echo "Finding old udev rules..."
+for c in /etc/udev/rules.d/9{0,9}-opentabletdriver.rules; do
+  if [ -f "${c}" ]; then
+    echo "Deleting ${c}"
+    rm "${c}"
+  fi
+done
+
+echo "Finding old kernel blacklist rules..."
+if [ -f /etc/modprobe.d/blacklist.conf ]; then
+  echo "Deleting /etc/modprobe.d/blacklist.conf"
+  rm /etc/modprobe.d/blacklist.conf
+done
+
+udevadm control --reload-rules && udevadm trigger
+```
+
+> This script cleans up obsolete udev rules and reloads udev.
+
+Then update the initramfs:
+
+| Distro | Command |
+| --- | --- |
+| Arch Linux | `sudo mkinitcpio -P` |
+| Debian/Ubuntu | `sudo update-initramfs -u` |
+
+For other distros, refer to your distro's documentation on how to update the initramfs.
+
+#### Non-standard FHS distro
+
+Refer to your distro's documentation on how to remove udev rules of the name `90-opentabletdriver.rules` or `99-opentabletdriver.rules`.
+
+### Built from source
+
+Make sure you built OpenTabletDriver via [these instructions](https://github.com/OpenTabletDriver/OpenTabletDriver#linux) and extracted the generic binary tarball correctly.
