 ## Installing Redis
 
 RedisVL requires a distribution of Redis that supports the [Search and Query](https://redis.com/modules/redis-search/) capability of which there are 3:
 
 offering
+
 1. [Redis Cloud](https://redis.io/cloud), a fully managed cloud offering
 2. [Redis Stack](https://redis.io/docs/getting-started/install-stack/docker/), a local docker image for testing and development
 3. [Redis Enterprise](https://redis.com/redis-enterprise/), a commercial self-hosted

 ### Redis Cloud
 
 Redis Cloud is the easiest way to get started with RedisVL. You can sign up for a free account [here](https://redis.io/cloud). Make sure to have the `Search and Query`
 capability enabled when creating your database.

 ### Redis Stack (local development)
 
 For local development and testing, Redis-Stack can be used. We recommend running Redis

 ### Redis Enterprise (self-hosted)
 
 Redis Enterprise is a commercial offering that can be self-hosted. You can download the latest version [here](https://redis.io/downloads/).
 
-If you are considering a self-hosted Redis Enterprise deployment on Kubernetes, there is the [Redis Enterprise Operator](https://docs.redis.com/latest/kubernetes/) for Kubernetes. This will allow you to easily deploy and manage a Redis Enterprise cluster on Kubernetes.

+
+### Redis Sentinel
+
+For high availability deployments, RedisVL supports connecting to Redis through Sentinel. Use the `redis+sentinel://` URL scheme to connect:
+
+```python
+from redisvl.index import SearchIndex
+
+# Connect via Sentinel
+# Format: redis+sentinel://[username:password@]host1:port1,host2:port2/service_name[/db]
+index = SearchIndex.from_yaml(
+    "schema.yaml",
+    redis_url="redis+sentinel://sentinel1:26379,sentinel2:26379/mymaster"
+)
+
+# With authentication
+index = SearchIndex.from_yaml(
+    "schema.yaml",
+    redis_url="redis+sentinel://user:pass@sentinel1:26379,sentinel2:26379/mymaster/0"
+)
+```
+
+The Sentinel URL format supports:
+
+- Multiple sentinel hosts (comma-separated)
+- Optional authentication (username:password)
+- Service name (required - the name of the Redis master)
+- Optional database number (defaults to 0)
