+## Plisio PHP API library
+
+To start using cryptocurrencies on your site you need to create an account on <https://plisio.net> and approve your domain under API setting page to get a **secret key**.
+
+This secret key will be used for creating instance of the PlisioClient.
+
+### Installation
+
+**Composer**
+
+You can install library via [Composer](http://getcomposer.org/). Run the following command in your terminal:
+
+```bash
+composer require plisio/plisio-api-php
+```
+
+Usage example:
+
+```
+$secretKey = 'xxxxx';
+
+$plisio = new \Plisio\ClientAPI($secretKey);
+$plisio->getBalances('BTC');
+```
+
+New order:
+
+```
+require_once dirname(__FILE__) . DIRECTORY_SEPARATOR . 'vendor' . DIRECTORY_SEPARATOR . 'autoload.php';
+
+$secretKey = 'xxxxx';
+$request = [
+          'amount' => float, // required Invoice amount in selected currency OR amount_usd can be used instead
+//          'amount_usd' => float, // required Invoice amoint in USD
+          'currency' => string, // required (ETH, BTC, LTC, TZEC, DOGE, BCH, ...)
+          'order_number' => string, // required Client's internal ID
+          'order_name' => string, // required Client's internal name
+          'description' => string, // optional any description
+          'callback_url' => string, // optional Absolute URL where Plisio will send updates
+          'success_url' => string, // optional Absolute URL of the final (success) invoice link
+          
+];
+
+$plisio = new \Plisio\ClientAPI($secretKey);
+$invoice = $plisio->createTransaction($request);
+
+if ($invoice && isset($invoice['status']) && $invoice['status'] == 'success') {
+   header('Location: ' . $invoice['data']['invoice_url']);
+} else {
+  print_r($invoice);
+}
+```
