-Sanitiser for OpenType
-----------------------
+OpenType Sanitiser
+==================
 
-(Idea from Alex Russell)
+The OpenType Sanitiser (OTS) parses and serialises OpenType files (OTF, TTF)
+and WOFF and WOFF2 font files, validating them and sanitising them as it goes.
 
-The CSS font-face property[1] is great for web typography. Having to use images
+The C library is integrated into Chromium and Firefox, and also simple
+command line tools to check files offline in a Terminal.

+The CSS [font-face property][1] is great for web typography. Having to use images
 in order to get the correct typeface is a great sadness; one should be able to
 use vectors.
 
-However, the TrueType renderers on many platforms have never been part of the
-attack surface before and putting them on the front line is a scary proposition.
-Esp on platforms like Windows where it's a closed-source blob running with high
-privilege.
+However, on many platforms the system-level TrueType font renderers have never
+been part of the attack surface before, and putting them on the front line is
+a scary proposition... Especially on platforms like Windows, where it's a
+closed-source blob running with high privilege.
 
-Thus, the OpenType Sanitiser (OTS) is designed to parse and serialise OpenType
-files, validating them and sanitising them as it goes.
