+A Raycast extension that helps monitor glucose data from Freestyle Libre 2 & 3 devices through LibreView integration.
 
-[Raycast](https://raycast.com/) lets you control your tools with a few keystrokes. This repository contains all extensions that are available in the [Raycast Store](https://raycast.com/store). It also includes documentation and examples of how to extend Raycast using React.
+## Important Note About Data Timing
 
-![Header](images/header.webp)
+Please be aware that the glucose readings shown in this extension may be slightly delayed compared to your actual sensor readings. This delay occurs because:
 
-## Getting Started
+1. The data comes from LibreView's servers, not directly from your sensor
+2. LibreView's API provides data that is typically 5-15 minutes behind real-time readings
+3. The sync frequency depends on your sensor's connection to your phone and the phone's connection to LibreView
 
-Visit [https://developers.raycast.com](https://developers.raycast.com) to get started with our API. If you want to discover and install extensions, check out [our Store](https://raycast.com/store).
+For the most up-to-date readings, please refer to your Libre sensor directly or the LibreLink app on your phone.
 
-Be sure to read and follow our [Community](https://manual.raycast.com/community-guidelines) and [Extension](https://manual.raycast.com/extensions) guidelines when submitting your extension and interacting with other folks in this repository.
+## Features
 
-## Feedback
+- 📊 Near real-time glucose monitoring through LibreView (5-15 minute delay)
+- 📈 24-hour glucose average with visual gauge
+- 🎯 Color-coded readings (In Range 🟢, Low 🟡, High 🔴)
+- 🔔 Menu bar quick view for latest readings
+- 🔄 Automatic updates every 5 minutes
+- 📱 Support for both mmol/L and mg/dL units
 
-Raycast wouldn't be where it is without the feedback from our community, so we would be happy to hear what you think of the API / DevX and how we can improve. Please use [GitHub issues](https://github.com/raycast/extensions/issues/new/choose) for everything API related (bugs, improvements suggestions, developer experience, docs, etc). We have a few [templates](https://developers.raycast.com/examples) that should help you get started.
+## Prerequisites
 
-## Community
+Before using this extension, you need:
 
-Join our [Slack community](https://raycast.com/community) to share your extension, debug nasty bugs or simply get to know like-minded folks.
+1. A LibreView account (https://www.libreview.com)
+2. The LibreLinkUp mobile app installed and configured
+3. A Freestyle Libre 2 or 3 sensor actively sharing data
+4. Raycast installed on your Mac (https://raycast.com)
+
+## Setup Instructions
+
+1. Install the extension from the Raycast Store
+2. Configure the required preferences:
+   - LibreView Username (your account email)
+   - LibreView Password
+   - Preferred Glucose Unit (mmol/L or mg/dL)
+3. If you haven't set up LibreLinkUp sharing:
+   1. Download the LibreLinkUp app
+   2. Log in with your LibreView credentials
+   3. Add the account that has the Libre sensor
+   4. Wait for them to accept the invitation
+   5. Once connected, the extension will start showing data
+
+## LibreView API Requirements
+
+This extension uses the LibreView API with the following specifications:
+
+- Authentication: Token-based with 50-minute expiry
+- Rate Limiting: Implements automatic retry with 1-minute delay
+- Data Refresh: Every 5 minutes for menu bar updates
+- Data Latency: Readings may be 5-15 minutes behind real-time sensor data
+- API Endpoints Used:
+  - Login: `/llu/auth/login`
+  - Connections: `/llu/connections`
+  - Glucose Data: `/llu/connections/{patientId}/graph`
+
+## Privacy Policy
+
+SugarDaddyDiabetes takes your privacy and data security seriously:
+
+1. Data Collection
+   - The extension only collects necessary glucose data from LibreView
+   - No personal data is stored locally
+   - Credentials are securely stored in Raycast's preference system
+
+2. Data Handling
+   - All data is fetched in real-time from LibreView
+   - No historical data is cached or stored
+   - Data is only displayed within the Raycast interface
+
+3. Data Transmission
+   - All API communications use secure HTTPS
+   - Authentication tokens are stored temporarily in memory
+   - No data is shared with third parties
+
+4. Security Measures
+   - Credentials are stored securely using Raycast's encryption
+   - API tokens expire after 50 minutes
+   - Rate limiting protection is implemented
+   - No sensitive data is logged or stored
