+
+## Features
+
+- **Instant search** — filter glyphs by name or codepoint (`U+E000`) as you type, with results capped at 200 for snappy performance
+- **Live SVG previews** — each glyph is rendered on the fly from the actual font outlines via `opentype.js`; no image assets required
+- **Rich detail panel** — shows a large preview alongside name, codepoint, Unicode escape, HTML entity, and the raw glyph character
+- **Multiple copy actions** — copy the glyph character, codepoint, name, or Unicode escape sequence, with an option to close Raycast immediately after copying
+- **Configurable icon colour** — choose white or black rendering to suit your Raycast theme
+- **Local-only, no network** — reads fonts directly from `~/Library/Fonts` and caches metadata in `~/.cache/nerd-font-picker/glyphs.json`; nothing leaves your machine
+- **One-command cache refresh** — rebuild the glyph index at any time from the action panel if you install a new font
+
+---
+
+## Requirements
+
+- [Raycast](https://www.raycast.com/) installed
+- At least one Nerd Font installed in `~/Library/Fonts` whose filename ends in `NerdFontMono-Regular.ttf` or `NerdFont-Regular.ttf`
+
+Popular choices from [nerdfonts.com](https://www.nerdfonts.com/): JetBrains Mono Nerd Font, FiraCode Nerd Font, Hack Nerd Font. Any variant that ships the standard Nerd Font PUA block (`U+E000`–`U+F8FF`) will work.
+
+---
+
+## Quick Start
+
+1. Open Raycast and search for **"Nerd Font Glyphs"**
+2. On first run the extension scans your installed font and writes a cache — this takes a few seconds and shows a progress toast
+3. Browse or search the glyph list; the detail panel updates in real time
+4. Press `Return` to copy the glyph and close, or open the action panel (`Cmd+K`) for more copy options
+

+
+## Usage
+
+### Searching
+
+Type freely in the search bar to filter by glyph name or codepoint:
+
+| Query    | Matches                                 |
+| -------- | --------------------------------------- |
+| `arrow`  | All glyphs whose name contains "arrow"  |
+| `U+E0A0` | Exact codepoint lookup                  |
+| `e0a`    | Partial codepoint match                 |
+| `nf-dev` | Name-prefix filtering (Devicons family) |
+
+### Detail Panel
+
+Selecting any glyph opens a split detail view showing:
+
+| Field          | Example            |
+| -------------- | ------------------ |
+| Name           | `nf-dev-git`       |
+| Codepoint      | `U+E0A0`           |
+| Unicode Escape | ``                |
+| HTML Entity    | `&#xE0A0;`         |
+| Glyph          | `` (raw character) |
+
+### Action Panel (`Cmd+K`)
+
+| Action              | Description                                                             |
+| ------------------- | ----------------------------------------------------------------------- |
+| Copy Glyph & Close  | Copies the raw glyph character and dismisses Raycast                    |
+| Copy Glyph          | Copies the raw glyph character and stays open                           |
+| Copy Codepoint      | Copies `U+E0A0`                                                         |
+| Copy Name           | Copies the glyph name string                                            |
+| Copy Unicode Escape | Copies `` (or `\Uxxxxxxxx` for higher planes)                          |
+| Refresh Cache       | Re-parses the font and rebuilds `~/.cache/nerd-font-picker/glyphs.json` |
