-# Obsidian Sample Plugin
+# Unicode Text Formatter
 
-This is a sample plugin for Obsidian (https://obsidian.md).
+An [Obsidian](https://obsidian.md) plugin that transforms selected text into Unicode Mathematical Alphanumeric Symbols — Sans-Serif Bold, Italic, and Bold-Italic — for use in LinkedIn and Facebook posts.
 
-This project uses TypeScript to provide type checking and documentation.
-The repo depends on the latest plugin API (obsidian.d.ts) in TypeScript Definition format, which contains TSDoc comments describing what it does.
+## Features
 
-This sample plugin demonstrates some of the basic functionality the plugin API can do.
-- Adds a ribbon icon, which shows a Notice when clicked.
-- Adds a command "Open modal (simple)" which opens a Modal.
-- Adds a plugin setting tab to the settings page.
-- Registers a global click event and output 'click' to the console.
-- Registers a global interval which logs 'setInterval' to the console.
+- **Unicode Bold** — converts letters and digits to sans-serif bold (𝗔𝗕𝗖 / 𝗮𝗯𝗰 / 𝟬𝟭𝟮)
+- **Unicode Italic** — converts letters to sans-serif italic (𝘈𝘉𝘊 / 𝘢𝘣𝘤)
+- **Unicode Bold Italic** — converts letters to sans-serif bold italic (𝘼𝘽𝘾 / 𝙖𝙗𝙘)
+- Non-mapped characters (punctuation, spaces, emoji, etc.) are passed through unchanged
 
-## First time developing plugins?
+## Usage
 
-Quick starting guide for new plugin devs:
+1. Select text in the editor
+2. Open the Command Palette (`Ctrl/Cmd + P`)
+3. Run one of:
+   - **Format as Unicode Bold**
+   - **Format as Unicode Italic**
+   - **Format as Unicode Bold Italic**
 
-- Check if [someone already developed a plugin for what you want](https://obsidian.md/plugins)! There might be an existing plugin similar enough that you can partner up with.
-- Make a copy of this repo as a template with the "Use this template" button (login to GitHub if you don't see it).
-- Clone your repo to a local development folder. For convenience, you can place this folder in your `.obsidian/plugins/your-plugin-name` folder.
-- Install NodeJS, then run `npm i` in the command line under your repo folder.
-- Run `npm run dev` to compile your plugin from `main.ts` to `main.js`.
-- Make changes to `main.ts` (or create new `.ts` files). Those changes should be automatically compiled into `main.js`.
-- Reload Obsidian to load the new version of your plugin.
-- Enable plugin in settings window.
-- For updates to the Obsidian API run `npm update` in the command line under your repo folder.
+The selected text is replaced in place with its Unicode equivalent.
 
-## Releasing new releases
+## Installation
 
-- Update your `manifest.json` with your new version number, such as `1.0.1`, and the minimum Obsidian version required for your latest release.
-- Update your `versions.json` file with `"new-plugin-version": "minimum-obsidian-version"` so older versions of Obsidian can download an older version of your plugin that's compatible.
-- Create new GitHub release using your new version number as the "Tag version". Use the exact version number, don't include a prefix `v`. See here for an example: https://github.com/obsidianmd/obsidian-sample-plugin/releases
-- Upload the files `manifest.json`, `main.js`, `styles.css` as binary attachments. Note: The manifest.json file must be in two places, first the root path of your repository and also in the release.
-- Publish the release.
+### Manual
 
-> You can simplify the version bump process by running `npm version patch`, `npm version minor` or `npm version major` after updating `minAppVersion` manually in `manifest.json`.
-> The command will bump version in `manifest.json` and `package.json`, and add the entry for the new version to `versions.json`
+1. Build the plugin (see [Development](#development)) or download a release
+2. Copy `main.js` and `manifest.json` to your vault at:
+   ```
+   <VaultFolder>/.obsidian/plugins/unicode-text-formatter/
+   ```
+3. In Obsidian: **Settings → Community Plugins → Installed Plugins** — enable **Unicode Text Formatter**
 
-## Adding your plugin to the community plugin list
+## Development
 
-- Check the [plugin guidelines](https://docs.obsidian.md/Plugins/Releasing/Plugin+guidelines).
-- Publish an initial version.
-- Make sure you have a `README.md` file in the root of your repo.
-- Make a pull request at https://github.com/obsidianmd/obsidian-releases to add your plugin.
+Requirements: Node.js ≥ 16
 
-## How to use
-
-- Clone this repo.
-- Make sure your NodeJS is at least v16 (`node --version`).
-- `npm i` or `yarn` to install dependencies.
-- `npm run dev` to start compilation in watch mode.
-
-## Manually installing the plugin
-
-- Copy over `main.js`, `styles.css`, `manifest.json` to your vault `VaultFolder/.obsidian/plugins/your-plugin-id/`.
-
-## Improve code quality with eslint
-- [ESLint](https://eslint.org/) is a tool that analyzes your code to quickly find problems. You can run ESLint against your plugin to find common bugs and ways to improve your code. 
-- This project already has eslint preconfigured, you can invoke a check by running`npm run lint`
-- Together with a custom eslint [plugin](https://github.com/obsidianmd/eslint-plugin) for Obsidan specific code guidelines.
-- A GitHub action is preconfigured to automatically lint every commit on all branches.
-
-## Funding URL
-
-You can include funding URLs where people who use your plugin can financially support it.
-
-The simple way is to set the `fundingUrl` field to your link in your `manifest.json` file:
-
-```json
-{
-    "fundingUrl": "https://buymeacoffee.com"
-}
+```bash
+npm install
+npm run dev     # watch mode — recompiles on save
+npm run build   # one-time production build
+npm run lint    # ESLint check
 ```
 
-If you have multiple URLs, you can also do:
+### Project structure
 
-```json
-{
-    "fundingUrl": {
-        "Buy Me a Coffee": "https://buymeacoffee.com",
-        "GitHub Sponsor": "https://github.com/sponsors",
-        "Patreon": "https://www.patreon.com/"
-    }
-}
-```
+| File | Purpose |
+|------|---------|
+| `src/unicode-maps.ts` | Builds character lookup maps from Unicode code point ranges |
+| `src/formatter.ts` | `transformText(text, style)` — maps each character through the selected style map |
+| `src/commands.ts` | Registers the three editor commands with the Obsidian plugin API |
+| `src/main.ts` | Plugin entry point — calls `registerCommands` on load |
+
+### Unicode blocks used
+
+| Style | Uppercase | Lowercase | Digits |
+|-------|-----------|-----------|--------|

+
+## Releasing
+
+1. Update `manifest.json` with the new version and minimum Obsidian version
+2. Update `versions.json`: `"new-version": "min-obsidian-version"`
+3. Create a GitHub release tagged with the exact version number
+4. Attach `manifest.json` and `main.js` as release assets
+
+> You can bump the version automatically:
+> ```bash
+> npm version patch   # or minor / major
+> ```
