+:END:
+By default, Neofetch will display ascii art next to our system information
+representing our distro’s logo. We’ll customize it a bit. First, let’s change
+the ~backend~ value. Note that most of them (except ~off~ of course) support
+shorthands such as ~--kitty~ when passed as arguments from the command line. In
+my case, I will use the Kitty backend since it is the native backend of the
+terminal emulator I use.
+- Default value :: ~"ascii"~
+- Values ::
+  - ~ascii~
+  - ~caca~

+- flag :: ~--backend~
+#+BEGIN_SRC sh
+  image_backend="kitty"
+#+END_SRC
+
+Now, since I indicated I wanted an image engine, I’ll indicate neofetch which
+image to find. Note that ~auto~ will pick the best image source for whatever
+image backend is used. In ascii mode, distro ascii art will be used and in an
+image mode, your wallpaper will be used.
+- Default value :: ~auto~

+The default image size will probably not be correct since it is half the
+terminal width and I have an ultrawide monitor, so I’ll need to set it manually.
