 ## Features
 
 ### Unlimited Alarms & Tracking
+
 - You can set **as many alarms as you like** — no daily or total limit.
 - Track **any number of cryptocurrencies** in the list simultaneously.

 ### Price Updates
+
 - **Binance** and **OKX** are integrated as the primary data sources.
 - By default, HodlEye tries Binance first; if that fails or is forced off, it falls back to OKX.

 If you prefer not to keep the HodlEye Crypto Price Tracker web interface open in your browser all the time, you can use a lightweight Windows application called **HodlEye_Notify**. This tool connects directly to the same endpoint as the Docker container and will display notifications on your desktop whenever an alarm is triggered.
 
-1. **Setup**  
-   - Enter the IP address and port of your HodlEye Docker container (for example, `http://192.168.1.112:3099/`) in the HodlEye_Notify window.  
-   - Click **Connect** to establish a WebSocket connection.  
-   - Once connected, you’ll see the status change to “Connected.”
+&nbsp;
+1.  **Setup**
 
-2. **Autostart**  
-   - Add HodlEye_Notify to your Windows **Startup** folder so it automatically launches when Windows starts. This way, you’ll continuously receive notifications without needing to reopen the program manually.

-     ```
-   - If everything is configured correctly, you should receive a desktop notification from HodlEye_Notify indicating the alarm has triggered.

 ## Important Notes / Limitations
 
-1. **5-second polling**  
-   - There’s a potential delay in alarms because price thresholds are only checked every 5 seconds. If a price briefly touches and moves away between polls, you might miss that exact trigger moment.
+1. **1-second polling**
+
+   - There’s a potential delay in alarms because price thresholds are only checked every 1 seconds. If a price briefly touches and moves away between polls, you might miss that exact trigger moment.
 
 2. **API availability**
+
    - Binance/OKX may be temporarily down or might not support certain symbols.
    - HodlEye tries Binance → fallback to OKX if needed.
 
 3. **Unlimited Alarms (Once vs. Recurring)**
+
    - **Once** alarms become locally “triggered” to avoid repeated alerts but are not server-side deactivated.
    - **Recurring** triggers repeatedly every time the threshold is crossed.
