+### CORE FONTS
+There are two ways of adding fonts, with __Fontconfig__ or with __X__ core fonts. The next deals with core fonts.
+* Fonts can be added to the database on _"/etc/X11/xorg.conf"_ or in the separate file _"/etc/X11/xorg.conf.d/fonts.conf_".
+* Supported font formats are _BDF_, binary _PCF_, and _SNF_.
+* Scalable fonts must appear in the font path before the bitmap fonts when possible.
+
+__STEP 1__: Create a font directory with font files and index files.
+* If there are scalable fonts you might first need to correctly name them index first:  
+`mkfontscale ~/.fonts`  
+* To properly create a font index file:  
+`mkfontdir ~/.fonts`  
+Some files are creat with this
+* The _fonts.dir_ lists the available fonts in this directory.
+* The _fonts.alias_ provides aliases.
+
+__STEP 2__: Inform __X__ where to look for font directories.
+* Edit _"/etc/X11/xorg.conf"_ or in the separate file _"/etc/X11/xorg.conf.d/fonts.conf"_
