+# Discord Emojis
+
+A Python tool that automatically fetches and extracts the latest emoji data from Discord.
+
+## Overview
+
+This project automatically downloads the latest Discord build from the [Discord-Datamining](https://github.com/Discord-Datamining/Discord-Datamining) repository, extracts emoji data, and saves it in a structured JSON format. It runs as a GitHub Actions workflow twice a week to keep the emoji data up-to-date without manual intervention.
+
+## How It Works
+
+- GitHub Actions workflow runs automatically twice per week
+- Downloads the latest Discord build
+- Extracts emoji information
+- Saves data in a standardized JSON format
+- Tracks changes using hash comparison to avoid unnecessary updates
+- Detects and reports UTF-16 surrogate pairs
+
+## Technical Details
+
+The project uses:
+- Python 3.13+
+- Dependencies:
+  - json5
+  - orjson
+  - requests
+
+## Output
+
+The emoji data is saved in `build/emojis.json` in the following format:
+```json
+{
+    "emojis": [
+        {
+            "name": "emoji_name",
+            "id": "emoji_id",
+            ...
+        },
+        ...
+    ]
+}
+```
+
+The main emojis.json file in the root directory is the updated version that consumers can access via GitHub raw URLs or by cloning this repository.
+
+## Development
+
+For local development or testing:
+
+```bash
+# Install dependencies using uv
+uv sync --dev
+
+# Run the update script manually
+uv run src
+```
+
+Note: Local execution should only be done during development. In production, the script runs automatically through GitHub Actions.
+
+The script will:
+1. Download the latest Discord build
+2. Extract emoji information
+3. Save the data to `build/emojis.json`
+4. Generate a hash file to track changes
+
+If no changes are detected compared to the previous run, the script will exit with status code 3.
