 ## Description
 
-The glyphs of the *Last Resort* fonts are used as the backup of “last resort” to any other font: if a font cannot represent any particular Unicode character, the appropriate “missing” glyph from the *Last Resort* fonts is displayed instead. This provides users with the ability to more easily discern what type of character it is, and provides a clue as to what type of font they would need to display the characters properly. For more information, see *The Unicode Standard*, [Section 5.3](https://www.unicode.org/versions/Unicode15.0.0/ch05.pdf), *Unknown and Missing Characters*.

 ## Building the fonts from source
 
-**NOTE**: *The sources and build scripts may be added after Unicode Version 15.1.0 has been released (2023), and as time and resources permit.*
+**NOTE**: *Building the fonts from source requires that [Python Version 3](https://www.python.org/) and [AFDKO](https://github.com/adobe-type-tools/afdko) (Adobe Font Development Kit for OpenType) be installed.*
 
-Updated TrueType fonts may be issued shortly after a new version of the Unicode Standard has been released.
+To build the fonts from source, simply execute the `build.sh` file.
