 ## Usage
 
-The FontLink's interface consists of two lists. The left one contains font
-sets; the right one shows fonts of the selected set.

-To add fonts to a set, use the button below the font list, the context menu,
-or drop them from your file manager anywhere on the FontLink's window. You can
-add the same font in several sets. Disabling or removing such a font from one
-set will not unlink it if it's still enabled in others.

-If a font is already installed on your system, it will appear as “inactive”
-and its checkbox will always be enabled. Check its pop-up tooltip to see
-where it is installed.
+A font appearing as "inactive" (grayed out) means that either the
+font with the same name is already installed on your system, or the
+file doesn't exist, e.g. it has been moved since the last time you
+used the program. Check the pop-up tooltip for more information.
 
-It's recommended to set up your fonts *before* running a program that will
-use them, because not all programs can update the list of fonts at runtime.

-If you want to add FontLink to autostart, don't forget to add `--minimized`
-or `-m` argument to start the program with the hidden window.
