+### Redis Modules Requirements
+
+**IMPORTANT:** This library requires Redis with the following modules:
+
+- **RedisJSON** - For storing and manipulating JSON data
+- **RediSearch** - For search and indexing capabilities
+
+#### Redis 8.0+
+
+If you're using Redis 8.0 or higher, both RedisJSON and RediSearch modules are included by default as part of the core Redis distribution. No additional installation is required.
+
+#### Redis < 8.0
+
+If you're using a Redis version lower than 8.0, you'll need to ensure these modules are installed:
+
+- Use [Redis Stack](https://redis.io/docs/stack/), which bundles Redis with these modules
+- Or install the modules separately in your Redis instance
+
+Failure to have these modules available will result in errors during index creation and checkpoint operations.
