 Aiocache provides 3 main entities:
 
-- **backends**: Allow you specify which backend you want to use for your cache. Currently supporting: SimpleMemoryCache, RedisCache using redis_ and MemCache using aiomcache_.
+- **backends**: Allow you specify which backend you want to use for your cache. See the docs for a full list of supported backends.
 - **serializers**: Serialize and deserialize the data between your code and the backends. This allows you to save any Python object into your cache. Currently supporting: StringSerializer, PickleSerializer, JsonSerializer, and MsgPackSerializer. But you can also build custom ones.
 - **plugins**: Implement a hooks system that allows to execute extra behavior before and after of each command.
