+Realtek RTL8821CE Driver maintained by Tomás Pinho for Arch Linux.
+Still, can serve Slackers as well!
+
+NOTE:
+
+  Although the driver builds for kernel 4.4.x as found in -14.2,
+  I only tested it in the field on kernel 5.4.x as found in -current.
+  Also, upstream warns that the source is targeting kernels > 4.14.
+
+To build the package for a kernel different from the running one,
+start the script setting the KERNEL variable as in:
+
+  KERNEL=4.4.14 ./rtl8821ce.SlackBuild
+
+NOTE:
+
+1. If you experience problems using this driver (e.g. a non-working
+   WiFi or Bluetooth), visit project's homepage to learn about possible
+   solutions.
+2. If you want to use this driver on -14.2, but with the kernel from
+   -current, you will need to compile the kernel yourself on -14.2.
+   Otherwise, you will run into compilation errors while building
+   the driver. I have no intent of fixing that, unless you provide me
+   with a working patch. ;-)

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
