## What it is
A project that generates OpenType versions of the commercial Operator Mono font with programming ligatures similar to Fira Code, including italic variants. Ligatures are custom-designed in Glyphs and built via a JavaScript font-generation pipeline.

## Use cases
- add Fira Code-style ligatures to Operator Mono
- get italic ligatures for Operator Mono
- make my code editor font show ligatures
- generate Operator Mono font with ligature support
- fix cursor position inside ligatures in Operator Mono

## When to choose
- you own a license for Operator Mono and want ligatures
- you want Fira Code-like ligatures while keeping Operator Mono's look
- you need italic ligature variants

## When to avoid
- you don't own Operator Mono (it's a commercial font)
- you need font weights not yet covered by the project
- you want a free font with ligatures out of the box
- you don't have access to macOS and Glyphs to regenerate missing weights
