WHICH FILES TO USE

Desktop (.ttf)
Install these files for Word, PowerPoint, Keynote, Adobe applications, and
other desktop publishing tools. Static TrueType files provide broad office
compatibility and expose only the approved brand weights.

Web (.woff2)
Use these optimized Latin webfonts in websites and web applications. Do not
install WOFF2 files as desktop fonts. Keep the included font-family names,
weights, and styles when defining @font-face rules.

INSTALLING DESKTOP FONTS

macOS
1. Unzip the desktop kit.
2. Double-click each .ttf file and choose Install Font in Font Book.
3. Restart any open Office or design applications.

Windows
1. Unzip the desktop kit.
2. Select the .ttf files, right-click, and choose Install for all users when
   available.
3. Restart any open Office or design applications.

When sharing editable documents or presentations, confirm that the recipient
has the fonts installed or use the application's supported font-embedding
option. For a fixed final deliverable, export a PDF and inspect it before
sending.
