+======Installing Memcached======
+You can install Memcached, or LiteSpeed's version of Memcached, LSMCD.
 =====Install LiteSpeed Memcached=====
-LSMCD is a high-performance, distributed caching system with file-backed shared memory, generic in nature, but originally intended for use in speeding up dynamic web applications by alleviating database load. It is designed as a drop-in replacement for Memcached, however we also have a few features that Memcached does not: High-Availability and persistence of data. High-Availability means that if one or more of your servers go down, your data can still be accessed and updated as though it was still up. Persistence of data means that there is no need for a database backend. Whatever you put in LSMCD stays in LSMCD unless you say otherwise.
