+Detect potentially malicious PHP files.
+```
+
+## What does it detect?
+
+PHP-malware-finder does its very best to detect obfuscated/dodgy code as well as
+files using PHP functions often used in malwares/webshells.
+
+The following list of encoders/obfuscators/webshells are also detected:
+
+* [Best PHP Obfuscator]( http://www.pipsomania.com/best_php_obfuscator.do )
+* [Carbylamine]( https://code.google.com/p/carbylamine/ )
+* [Cipher Design]( http://cipherdesign.co.uk/service/php-obfuscator )
+* [Cyklodev]( http://sysadmin.cyklodev.com/online-php-obfuscator/ )
+* [Joes Web Tools Obfuscator]( http://www.joeswebtools.com/security/php-obfuscator/ )
+* [Php Obfuscator Encode]( http://w3webtools.com/encode-php-online/ )
+* [SpinObf]( http://mohssen.org/SpinObf.php )
+* [Weevely3]( https://github.com/epinna/weevely3 )
+* [atomiku]( http://atomiku.com/online-php-code-obfuscator/ )
+* [cobra obfuscator]( http://obfuscator.uk/example/ )
+* [phpencode]( http://phpencode.org )
+* [webtoolsvn]( http://www.webtoolsvn.com/en-decode/ )
+* [tennc]( http://tennc.github.io/webshell/ )
+* [web-malware-collection]( https://github.com/nikicat/web-malware-collection )
+
+
+Of course it's easy to bypass PMF, but its goal is to catch kiddies and idiots,
+not people with a working brain.
+
+## How does it work?
+
+Detection is performed by crawling the filesystem and testing files against a
+[set]( https://github.com/nbs-system/php-malware-finder/blob/master/malwares.yara )
+of [YARA](https://plusvic.github.io/yara/) rules. Yes, it's that simple!
+
+
+## How to use it?
+
+```
+$ ./phpmalwarefinder -h
+Usage phpmalwarefinder [-cfhw] <file|folder> ...
+        -c  Optional path to a configuration file
+        -f  Fast mode
+        -h  Show this help message
+    -t  Specify the number of threads to use (8 by default)
+        -v  Verbose mode
+```
+
+Or if you prefer to use `yara`:
+
+```
+$ yara -r ./malwares.yara /var/www
+```
+
+## Whitelisting
+
+Check the [whitelist.yara]( https://github.com/nbs-system/php-malware-finder/blob/master/whitelist.yara ) file.
+If you're lazy, you can generate whitelists for entire folders with the
+[generate_whitelist.py]( https://github.com/nbs-system/php-malware-finder/blob/master/generate_whitelist.py ) script.
