+# Analogo
+
+Minimal dependency to reset the content of the OPcache through PHP-FPM.
+
+## Installation
+
+    composer require dreadnip/analogo
+
+## Usage
+This tool only supports OPcache and fcgi/PHP-FPM.
+
+If no option is passed, it'll look for a php-fpm socket file in all the common places. If multiple are found, it'll try to select one for your PHP version.
+
+If no file can be found, it will default to 127.0.0.1:9000.
+
+Since this is a single-command application, you just need to call the binary:
+
+    php /path/to/your/project/vendor/bin/analogo
+
+You can also pass an IP address or a unix socket to the --fcgi option.
+
+    php /path/to/your/project/vendor/bin/analogo --fcgi=/var/run/php-fpm.sock
+
+## Credit
+
+This tool is of course inspired and based on the awesome [cachetool](https://github.com/gordalina/cachetool). All of the FCGI socket code is handled by [hollodotme/fast-cgi-client](https://github.com/hollodotme/fast-cgi-client).
