## What it is
A small installer (Ruby script plus font files) that replaces the Helvetica Neue system font on OS X 10.10 Yosemite with Apple's San Francisco typeface from the Apple Watch. It works by installing specially named fonts into /Library/Fonts so they take precedence over the system fonts.

## Use cases
- make my mac look like the apple watch font
- replace helvetica neue with san francisco on yosemite
- change system font on os x 10.10
- install san francisco font as system font
- customize mac ui typography

## When to choose
- you run OS X 10.10 Yosemite and want the San Francisco look
- you want a reversible, non-destructive system font swap

## When to avoid
- you run any macOS newer than Yosemite (San Francisco is built in)
- you need a maintained or licensed tool (no license, last release 2015)
- you want to use the fonts outside the system UI
