+  module Cache
+    # A cache store implementation which stores everything into memory in the
+    # same process. If you're running multiple Ruby on Rails server processes
+    # (which is the case if you're using mongrel_cluster or Phusion Passenger),
+    # then this means that your Rails server process instances won't be able
+    # to share cache data with each other. If your application never performs
+    # manual cache item expiry (e.g. when you're using generational cache keys),
+    # then using MemoryStore is ok. Otherwise, consider carefully whether you
+    # should be using this cache store.
+    #
+    # MemoryStore is not only able to store strings, but also arbitrary Ruby
+    # objects.
+    #
+    # MemoryStore is not thread-safe. Use SynchronizedMemoryStore instead
+    # if you need thread-safety.
