 ## Introduction
 
-Redis is a great database for use with Node.js. Both Redis Node.js share similar type conventions and threading models, which makes for a very predictable development experience. By pairing Node.js & Redis together you can achieve a scalable and productive development platform.
+Redis is a great database for use with Node.js. Both Redis and Node.js share similar type conventions and threading models, which makes for a very predictable development experience. By pairing Node.js and Redis together you can achieve a scalable and productive development platform.
 
-Redis Node.js has two primary clients available [node_redis](https://github.com/NodeRedis/node_redis) and [ioredis](https://github.com/luin/ioredis). Both are available through npm. Both clients have pros and cons, but we generally suggest node_redis, as it has wide support for Redis modules, it is easily extensible and widely used. Ioredis has better integrated support for the Redis Enterprise Cluster API, but this is only relevant if you're specifically using [the Cluster API topology](https://redis.com/redis-enterprise/technology/linear-scaling-redis-enterprise/) instead of the more common Proxy topology. Node_redis’ support for the Cluster API is provided by an additional shim, redis-clustr. Node_redis has built-in support for Redis Enterprise features such as [Active Active geo distribution](https://redis.com/redis-enterprise/technology/active-active-geo-distribution/), allowing you to have one database that spans multiple clusters. Node_redis also supports Redis-on-Flash which enables extending your database into Flash SSD storage for warm values and DRAM for hot values. Nodejs redis enables you to integrate such features.
