 ### Installing Debian package ###
 
-If you're using Debian or a derived distro, such as Ubuntu, please try using
-the experimental .deb package. If it works for you, this will remove the need
-to reinstall the driver after each kernel upgrade.
+If you're using Debian or a derived distro, such as Ubuntu, and are installing
+a release, please use the .deb package. If you're not using a Debian-based
+distro, or the .deb package didn't work, you can install the driver using
+DKMS, or manually, as described below.
 
-If you're not using a Debian-based distro, or the .deb package didn't work,
-you can try installing the driver using DKMS directly, if you know how, or
-manually as described below.

-### Installing source package with DKMS ###
+Source is either an unpacked release tarball (.tar.gz file), an unpacked
+source code archive downloaded from GitHub (.zip file), or source code checked
+out from Git.
 
-If you know how to use DKMS, you can try installing the package with it
-directly, employing the experimental DKMS support.
+Before installing from source in any way, make sure you have the headers for
+your kernel installed (on Debian-based systems):
 
-### DKMS issue preventing correct installation ###
+    sudo apt-get install -y "linux-headers-$(uname -r)"

+DKMS (Dynamic Kernel Module Support) is a system for installing out-of-tree
+Linux kernel modules, such as DIGImend kernel drivers. It helps make sure the
+modules are built with correct kernel headers and are properly installed, and
+also automatically reinstalls the modules when the kernel is updated.
 
-Be aware that the operation the above command does is inexact, and might not
-work, or might break DKMS. You've been warned. In any case, simply reinstall
-DKMS to restore it if something goes wrong.
+Installing with DKMS is the recommended way of installing development versions
+of DIGImend kernel drivers.
+
+To install with DKMS, make sure you have the `dkms` package installed (on
+Debian-based distros):
+
+    sudo apt-get install -y dkms
+
+or (on Fedora-based distros):
+
+    sudo dnf install -y dkms
 
-### Installing source package manually ###
+After that, run the following command from the source directory to install:
 
-To build the drivers run `make` in the package's directory.
+    sudo make dkms_install
 
-To install the drivers run `sudo make install` in the package's directory.
+Watch for any errors in the output, and if the drivers installed successfully,
+they will be automatically rebuilt and reinstalled each time the kernel is
+updated.
 
-Make sure the previous versions of the drivers were unloaded from memory with
-the following commands:
+#### Installing from source manually ####
 
-    sudo rmmod hid-kye

+To install from source manually, first build the drivers. Run the following
+command in the source directory:
 
-and reconnect the tablet. Or simply reboot the machine.
+    make
 
-Note that if you built and installed the driver with `make` and `sudo make

-upgrade.
+Then, to install the drivers, run this command in the same directory:
 
-### SSL errors during installation ###
+    sudo make install

+Note that if you built and installed the drivers this way, you will need to
