-A PHP API for antispam service cleantalk.org. Invisible protection from spam, no captches, no puzzles, no animals and no math.
+## The Invisible protection from spam, no captcha, no recaptcha, no puzzles, no math captcha.
+_API for antispam service cleantalk.org_
 
-## How API stops spam?
-API uses several simple tests to stop spammers.
-  * Spam bots signatures.
-  * Blacklists checks by Email, IP, web-sites domain names.
-  * JavaScript availability.
-  * Relevance test for the comment.
+#### Requirements
+* PHP 5.6 and above 
+* CURL support 
 
-## How API works?
-API sends a comment's text and several previous approved comments to the servers. Servers evaluates the relevance of the comment's text on the topic, tests on spam and finaly provides a solution - to publish or put on manual moderation of comments. If a comment is placed on manual moderation, the plugin adds to the text of a comment explaining the reason for the ban server publishing.
+### How we stop spam?
+PHP Anti-Spam library providing invisible spam protection for your websites, registration forms, and comment sections. CleanTalk API offers an effective CAPTCHA alternative that silently blocks spam without interrupting your users' experience.
 
-## Requirements
+When users submit forms on your website form, the form data is securely sent to CleanTalk’s cloud servers. CleanTalk analyzes submissions using advanced heuristics. CleanTalk then returns a real-time verdict— legitimate requests or spam.
 
-   * PHP 5.6 and above 
-   * CURL support 
+You are free to do anything with spam, or just allow as to block spam (we will interrupt desirable request).
 
-You can unpack the archive with the plugin to the root of the site or install it using the composer
 
+## Interesting? Let's make some settings (it will take few minutes)
+
+
+### Step 1 - install our SDK (2 variants ability)
+
+Through composer install **OR** through download zip arhive and unzip it to root directory (with your index.php)
 ```php
 composer require cleantalk/php-antispam
 ```
-
-### Sample SPAM test for text comment
-
-Notice: You can use the example PHP file from <code>./examples/form_with_handler</code>
 
-```php
-<?php
-session_start();
 
-$apikey = '';
-$email_field = 'name_email_form_field';
-$user_name_field = 'name_user_name_form_field';
-$message_field = 'name_message_form_field';
-$type_form = 'contact'; // use 'signup' for user signup form
+### Step 2 - add CleantalkAntispam handler (middleware/interception) to your form handler (action)
 
-// if downloaded, unzip and include the app, take your own relative path:
-require_once 'php-antispam/cleantalk-antispam.php';
-// if install the app by composer package:
-use Cleantalk\CleantalkAntispam;
+```php
+$apikey = ''; // get it here cleantalk.org (free trial)
+$email_field = $_POST['email']; // get it from your form
+$cleantalk_antispam = new CleantalkAntispam($apikey, $email_field);
+$api_result = $cleantalk_antispam->handle();
+```
 
-//require_once "lib/cleantalk-php-patch.php"; -- PHP-FPM
+### Step 2.1 - add js lib to your html template
+```html
+<script src="https://moderate.cleantalk.org/ct-bot-detector-wrapper.js"></script>
+```
+_Need for gathering frontend data._
 
-$cleantalk_antispam = new CleantalkAntispam($apikey, $email_field, $user_name_field, $message_field, $type_form);
-$api_result = $cleantalk_antispam->handle();
-if ($api_result) { // the check fired
-    if ($api_result->account_status !== 1) {
-        // something wrong with your key or license, to know why read $api_result->codes
-        echo 'Allowed. Spam protection disabled.'; // or do nothing
-    } else {
-        if ($api_result->allow === 1) {
-            echo 'Allowed. Spam protection OK.'; // or do nothing
-        } else {
-            die('Blocked. Spam protection OK. Reason: ' . $api_result->comment); // or make your own handler
-        }
-    }
+### Step 3 - do whatever you want with cloud result
+For example add die block for spam.
+```php
+if ($api_result && $api_result->allow === 0) {
+    die('Blocked. Spam protection OK. Reason: ' . $api_result->comment);
+    // or make your own actions/logs/messages ...
 }
-// your further code flow here
-?>
-
-<form method="post">
-    <label for="login">Login:</label>
-    <input type="text" name="name_user_name_form_field" id="login" />

-</form>
-
-<?php $cleantalk_antispam->frontendScript(); ?>
