+# Authsignal PHP SDK
+
+[![License](https://img.shields.io/packagist/l/authsignal/authsignal-php.svg)](https://github.com/authsignal/authsignal-php/blob/main/LICENSE)
 
 The official Authsignal PHP library for server-side applications. Use this SDK to easily integrate Authsignal's multi-factor authentication (MFA) and passwordless features into your PHP backend.
 
 ## Installation
 
-1. Add Authsignal's library to your project using Composer:
-
-   ```bash
-   composer require authsignal/authsignal-php
-   ```
-
-2. Run `composer update` to install the dependencies.
-3. Authsignal will now be autoloaded into your project.
-
-## Initialization
-
-Initialize the Authsignal SDK, ensuring you do not hard code the Authsignal Secret Key, always keep this safe.
-
-```php
-Authsignal::setApiSecretKey('secretKey');
+Using Composer:
+```bash
+composer require authsignal/authsignal-php
 ```
 
-You can find your `secretKey` in the [Authsignal Portal](https://portal.authsignal.com/organisations/tenants/api).
-
-## Region selection
-
-Authsignal has multiple api hosting regions. To view your hostname for your tenant, find it in the [Authsignal Portal](https://portal.authsignal.com/organisations/tenants/api).
-
-| Region      | Base URL                            |
-| ----------- | ----------------------------------- |
-| US (Oregon) | https://signal.authsignal.com/v1    |
-| AU (Sydney) | https://au.signal.authsignal.com/v1 |
-| EU (Dublin) | https://eu.signal.authsignal.com/v1 |
+## Getting Started
 
-You can set the hostname via the following code. If the `setApiUrl` function is not called, the api call defaults to the main Authsignal US region hostname `https://signal.authsignal.com`
-
-An example setting the client to use the AU region.
+Initialize the Authsignal client with your secret key from the [Authsignal Portal](https://portal.authsignal.com/) and the API URL for your region.
 
 ```php
-Authsignal::setApiUrl("https://au.signal.authsignal.com/v1");
-```
-
-Alternatively, an environment variable can be used to set the API URL:
+use Authsignal;
 
-```bash
-AUTHSIGNAL_API_URL=https://au.signal.authsignal.com/v1
+// Initialize the client
+Authsignal::setApiSecretKey(getenv('AUTHSIGNAL_SECRET_KEY'));
+Authsignal::setApiUrl(getenv('AUTHSIGNAL_API_URL')); // Use region-specific URL
 ```
 
-## Usage
-
-Authsignal's server side signal API has five main calls `track`, `getAction`, `getUser`, `enrollVerifiedAuthenticator`, `verifyChallenge`
-
-For more details on these api calls, refer to our [official PHP SDK docs](https://docs.authsignal.com/sdks/server/php#trackaction).
+### API URLs by Region
 
-### Response & Error handling
-
-Example:
-
-```php
-$result = Authsignal::updateAction(
-   userId: $userId,
-   action: $action,
-   idempotencyKey: "invalidKey",
-   attributes: ['state' => 'CHALLENGE_FAILED']
-);
-
-# PHP Fatal error: Uncaught AuthsignalNotFoundError: 404 - not_found
-```
