## Description

Signalgrid is a dedicated alerting bridge for WordPress developers. This plugin 
provides a direct pipeline between your WordPress site and the Signalgrid push notification
service, stripping away unnecessary complexity to focus on pure utility.

It is designed to stay out of your way, providing a clean, globally accessible PHP
function that allows you to trigger instant mobile alerts from anywhere within your
theme or custom plugin logic.

### Core Features

 * **Developer-Focused PHP Integration:** Adds a simple, global function to your
   WordPress site. Trigger a push notification with a single line of code inside
   your hooks, custom functions, or system logic.
 * **Instant Mobile Alerts:** Delivers high-priority notifications to iOS and Android
   devices, ensuring critical site events—like security triggers or system failures—
   are seen immediately.
 * **Top-Level Sidebar Menu:** Access your API configuration and documentation directly
   from the primary WordPress admin sidebar.

### Usage Example

To send a push notification, simply call the function anywhere in your code:

    ```
    <?php
        $channel = "df1741aabc93ce5fb7449435c266a8a3c5763b29";
        $title = "This is the title";
        $body = "This is the body";
        $severity = "INFO";
        $critical = false;

        if ( signalgrid_notify($channel, $title, $body, $severity, $critical) ) {
            // Notification sent successfully
        } else {
            // Error handling logic here
        }
    ?>
    ```

## Installation

 2. Activate the plugin through the ‘Plugins’ menu in WordPress.
 3. Locate the **Signalgrid** menu item in your WordPress sidebar.
