+
+# Example
+QuickSilver OSD is based on Roboto Mono font family:
+
+Symbols are included below, copy and paste them into the convertor.
+```
+abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890`-=[]\;',./~!@#$%^&*()_+{}|:"<> ?

+
+# Compiling
+
+Simply click convert then add the newly downloaded source file to the font directory and regenerate cmake via setup.sh

+In order to include the font in the HDZero Goggle Source code, you must forward declare the font source.
