## What it is
Iosevka is an open-source, highly customizable monospace and quasi-proportional typeface family designed for coding, terminals, and technical documents. The repository contains the font source and build tooling to generate customized font variants with configurable widths, weights, ligatures, and OpenType features.

## Use cases
- find a monospace programming font with ligatures
- customize a coding font with my own glyph styles
- get a narrow terminal font that fits more columns
- build a custom font variant from source
- choose a font for technical documents and terminals

## When to choose
- you want a slim monospace font that fits more columns on screen
- you need extensive customization of weights, widths, and ligature sets
- you want a free, open-source font under the SIL OFL license

## When to avoid
- you want a prebuilt font with no build step and minimal configuration
- you need proportional UI fonts rather than monospace/quasi-proportional designs
