-Lrujs is a fast and lightweight least-recently-used cache for [Node.js](http://nodejs.org)
+Lrujs is a fast and lightweight lru (least-recently-used) caching library for javascript.
+
+A LRU (least-recently-used) cache will automatically removes the least recently used data from cache when a new data is added to the cache and cache is full.
+
+Lrujs support TTL (Time to live) and max cache size feature.
+The default value for maxSize is 1000 and TTL is 0 milliseconds (0 means permanently), if you not set the max cache size and ttl then the default values are used.
+
+Lrujs is also support TTL, but it is not a TTL cache, and does not make strong TTL guarantees. Lrujs will not automatically removes the expired items, but you can set a default TTL on the cache or on a single value. If you do so, it will treat expired items as missing, and delete them when they are fetched. You can set TTL in milliseconds.
