% As introduced in the previous section, \textsf{luaotfload} uses a database
% to keep track of fonts available to \LuaTeX. Using this database, fonts can
% be loaded by font name as well as filename.
%
-% This font database is maintained automatically as you add and remove fonts
-% to/from your system. To update the database manually, run the script
-% |mkluatexfontdb| that is included with this package. If you have not run it
-% before, it may take quite some time to process every font on your computer.
+% When \textsf{luaotfload} is asked to load a font by font name, it will check
+% if font names database exists and load it, or generate a new database if non
+% exists. This is all done automatically without user intervention. When the
+% asked font is missing from the database, it will attempt to update the
+% database and try to find the font again, so that the user can install new
+% fonts without worrying about manually updating the database.
+%
+% However, it is sometimes desirable to update the database manually, so
+% \textsf{luaotfload} provides a |mkluatexfontdb| utility to manually update
+% the database. |mkluatexfontdb| is a lua script that can be either run
+% directly or as an argument to |texlua|, depending on your system\footnote{
+% On MS Windows it can be run either by calling the wrapper application
+% |mkluatexfontdb.exe| or with |texlua.exe mkluatexfontdb.lua|}.
+%
+% The first time the database is generated may take quite some time to process
+% every font on your computer.
% This is particularly noticeable if it occurs during a typesetting run.
% Subsequent runs to update the database will be quite fast, however.
