For those of you needing information about Grub,
this is written like the archwiki…
example:
7.2.2 FontsThe fonts GRUB uses “PFF2 font format” bitmap fonts. Fonts are specified with full fontnames. Currently there is no provision for a preference list of fonts, or deriving one fontfrom another. Fonts are loaded with the “loadfont” command in GRUB (Section 16.3.42[loadfont], page 75). To see the list of loaded fonts, execute the “lsfonts” command(Section 16.3.45 [lsfonts], page 76). If there are too many fonts to fit on screen, do “setpager=1” before executing “lsfonts”.
Is it okay? Or something wrong with it displaying? 
No it is o.k. but the way it is written is like some parts of Archwiki without any example and linking from one to the other complicated writing…
