# If a font renders properly w/hb-view but NOT in browser you probably have an OTS issue

• include image in project summary page
• include https://github.com/aravindavk/fontscripts
• include http://fuelproject.org/utrrs checks, also https://github.com/nandajavarma/Automated-Rendering-Testing/
• use a perceptial diff, taking inspiration from https://github.com/bslatkin/dpxdt
