+# Suppported signatures
+
+All supported signatures are HMAC signatures.
+
+## MD5
+
+Signs request with `HMAC-MD5`. Usage:
+
+```php
+<?php
+
+use ApiClients\Tools\Psr7\Oauth1\Definition;
+use ApiClients\Tools\Psr7\Oauth1\RequestSigning\RequestSigner;
+use ApiClients\Tools\Psr7\Oauth1\Signature\HmacMd5Signature;

+$requestSigner = new RequestSigner(
+    new Definition\ConsumerKey('consumer_key'),
+    $consumerSecret,
+    new HmacMd5Signature($consumerSecret)
+);
+```
+
+## SHA1
+
+Signs request using `HMAC-SHA1`. Usage:
+
+```php
+<?php
+
+use ApiClients\Tools\Psr7\Oauth1\Definition;
+use ApiClients\Tools\Psr7\Oauth1\RequestSigning\RequestSigner;
+use ApiClients\Tools\Psr7\Oauth1\Signature\HmacSha1Signature;

-        $consumerSecret  
-    )
+    new HmacSha1Signature($consumerSecret)
 );
+```
 
-// Pass it a PSR-7 request and it returns a signed PSR7 request you can use in any PSR7 capable HTTP client.
-$request = $requestSigner->withAccessToken(
-    new Definition\AccessToken('token_key'),
-    new Definition\TokenSecret('token_secret')
-)->sign($request);
+## SHA256
+
+Signs request using `HMAC-SHA256`. Usage:
+
+```php
+<?php
+
+use ApiClients\Tools\Psr7\Oauth1\Definition;
+use ApiClients\Tools\Psr7\Oauth1\RequestSigning\RequestSigner;
+use ApiClients\Tools\Psr7\Oauth1\Signature\HmacSha256Signature;

+$requestSigner = new RequestSigner(
+    new Definition\ConsumerKey('consumer_key'),
+    $consumerSecret,
+    new HmacSha256Signature($consumerSecret)
+);
+```
+
+## SHA384
+
+Signs request using `HMAC-SHA384`. Usage:
+
+```php
+<?php
+
+use ApiClients\Tools\Psr7\Oauth1\Definition;
+use ApiClients\Tools\Psr7\Oauth1\RequestSigning\RequestSigner;

+    new Definition\ConsumerKey('consumer_key'),
+    $consumerSecret,
+    new HmacSha384Signature($consumerSecret)
+);
+```
+
+## SHA512
+
+Signs request using `HMAC-SHA512`. Usage:
+
+```php
+<?php
+
+use ApiClients\Tools\Psr7\Oauth1\Definition;
+use ApiClients\Tools\Psr7\Oauth1\RequestSigning\RequestSigner;
