 For high-performance multimodal inference, Dynamo supports pre-computed embeddings with an **Encode-Prefill-Decode (EPD)** flow using **NIXL (RDMA)** for zero-copy tensor transfer.
 
-### Enabling the Feature
-
-This is an experimental feature that requires using a specific TensorRT-LLM commit.
-To enable it build the dynamo container with the `--tensorrtllm-commit` flag:
