## Introduction
JetBrains Mono was designed by the JetBrains type team to optimize readability during long coding sessions. It features a taller x-height than most monospaced fonts, making lowercase letters larger and easier to distinguish, while 138 code ligatures help reduce visual noise in common operator sequences.

## What JetBrains Mono Does
- Provides a monospaced typeface optimized for code readability at typical editor sizes
- Includes 138 programming ligatures (==, !=, =>, ->, etc.) rendered in a single glyph space
- Ships 8 weights from Thin to ExtraBold, each with matching italics
- Covers Latin Extended, Greek, Cyrillic, and many symbols
- Offers a "No Ligatures" variant (JetBrains Mono NL) for developers who prefer plain glyphs

## Architecture Overview
The font is designed in Glyphs.app and built via a custom Python toolchain that generates static OTF/TTF and variable font formats. Ligatures are implemented as OpenType contextual alternates (calt feature), allowing them to be toggled per-editor without modifying the font. Variable font axes cover weight only.

## Self-Hosting & Configuration
- Download TTF/OTF files from GitHub Releases and install system-wide or per-user
- On Linux, copy to ~/.local/share/fonts/ and run `fc-cache -f`
- Enable ligatures in your editor (VS Code: editor.fontLigatures = true)
- Use the NL (No Ligatures) variant if you prefer all characters displayed individually
- Pair with Nerd Fonts patcher if you need Powerline/devicon glyphs

## Key Features
- Increased x-height: lowercase letters occupy more vertical space for better legibility
- Character disambiguation: distinct forms for 1/l/I, 0/O, and similar pairs
- 138 code ligatures that maintain monospaced alignment
- Variable font support for fine-grained weight tuning
- Apache 2.0 license: free for all uses including commercial and embedding

## Comparison with Similar Tools
- **Fira Code** — pioneered ligatures in coding fonts; slightly wider; no variable font
- **Iosevka** — narrower and fully customizable via build system; more complex to set up
- **Cascadia Code** — Microsoft's default for Windows Terminal; similar quality, different aesthetics
- **Source Code Pro** — Adobe's monospace; no ligatures, wider character set
- **Victor Mono** — distinguishes with cursive italics; more stylistic, less neutral

## FAQ
**Q: How do I disable ligatures but keep the font?**
A: Either use the JetBrains Mono NL variant, or disable ligatures in your editor settings.

**Q: Is JetBrains Mono only for JetBrains IDEs?**
A: No. It works in any editor or terminal that supports TrueType/OpenType fonts.

**Q: Does it support Nerd Font icons?**
A: Not natively. Patch it with the Nerd Fonts patcher or use a pre-patched community build.

**Q: What is the recommended font size?**
A: The increased x-height means it looks good at smaller sizes (12-14px) where other fonts become hard to read.
