+Notice: An updated standards compliant (mac80211), in-kernel driver for
+rtl8821/11cu chipset based adapters and modules is available and as of
+kernel 6.12 is of good quality. If your distro uses kernel 6.12 or
+later, there is no need to install this driver. The in-kernel driver is
+part of the rtw88 series of drivers. The in-kernel driver is Linux
+Standards compliant (mac80211) and is a much better driver than this
+one. This driver will no longer get API related updates beyond kernel
+6.14 (unless provided by a user). If you use a kernel prior to 6.14, it
+is possible to use the new standards compliant driver by going to the
+following repo:
+
+https://github.com/lwfinger/rtw88
+
+If you decide to use the in-kernel driver, remember to first remove the
+driver in this repo. You can run the following to remove the driver in
+this repo:
+
+$ sudo sh remove-driver.sh
+
+It has been my pleasure to maintain this driver for the last several
+years. Thanks to all of those who helped.
+
+Remember: Ask not what your operating system can do for you, but
+what you can do for your operating system.
