+
+**Memcached** is a general-purpose distributed memory caching system. It is often used to speed up dynamic database-driven websites by caching data and objects in RAM to reduce the number of times an external data source (such as a database or API) must be read. Memcached is free and open-source software, licensed under the Revised BSD licence. Memcached runs on Unix-like operating systems (at least LINUX and OS X) and on Microsoft windows.
+
+We can store data to memcached server in key pair format. So whenever any request come from the app can be matched with memcached server without any query from mysql/Nosql server. This increases the performance of the application.
+
+**Installation**
+
+```bash
+npm install memcached
+```
+
+**Setting up the client**
+
+The constructor of the memcached client take 2 different arguments server locations and options. Syntax:
+
+```bash
+var Memcached = require('memcached');
+var memcached = new Memcached(Server locations, options);
+```
+
+**Example usage**:
+
+```js
+var Memcached = require('memcached');
+// all global configurations should be applied to the .config object of the Client.
+Memcached.config.poolSize = 25;
+
+var memcached = new Memcached('localhost:11211', {retries:10,retry:10000,remove:true,failOverServers:['192.168.0.103:11211']});
+```
