 # Indexes
+
 Operations related to the building and managing of Pinecone indexes are called [control plane](https://docs.pinecone.io/reference/api/introduction#control-plane) operations.
 
 ## Create Index
+
 You can use the Java SDK to create two types of indexes: [serverless indexes](https://docs.pinecone.io/guides/indexes/understanding-indexes#serverless-indexes) (recommended for most use cases) and 
 [pod-based indexes](https://docs.pinecone.io/guides/indexes/understanding-indexes#pod-based-indexes) (recommended for high-throughput use cases).
 
 ### Create a serverless index
+
 The following is an example of creating a serverless index in the `us-west-2` region of AWS. For more information on 
 serverless and regional availability, see [Understanding indexes](https://docs.pinecone.io/guides/indexes/understanding-indexes#serverless-indexes).
