-FlexFlow is a deep learning framework that accelerates distributed DNN training by automatically searching for efficient parallelization strategies. FlexFlow provides a drop-in replacement for PyTorch and TensorFlow Keras. Running existing PyTorch and Keras programs in FlexFlow only requires [a few lines of changes to the program](https://flexflow.ai/keras).
+> [!WARNING]
+> The FlexFlow repository has been split into separate [flexflow-train](https://github.com/flexflow/flexflow-train) and [flexflow-serve](https://github.com/flexflow/flexflow-serve) repositories.
+> You are currently viewing [flexflow-train](https://github.com/flexflow/flexflow-train). 
+> For anything inference/serving-related, go to [flexflow-serve](https://github.com/flexflow/flexflow-serve).

 ## Install FlexFlow
 To install FlexFlow from source code, please read the [instructions](INSTALL.md). If you would like to quickly try FlexFlow, we also provide pre-built Docker packages ([flexflow-cuda](https://github.com/flexflow/FlexFlow/pkgs/container/flexflow-cuda) with a CUDA backend, [flexflow-hip_rocm](https://github.com/flexflow/FlexFlow/pkgs/container/flexflow-hip_rocm) with a HIP-ROCM backend) with all dependencies pre-installed (N.B.: currently, the CUDA pre-built containers are only fully compatible with host machines that have CUDA 11.7 installed), together with [Dockerfiles](./docker) if you wish to build the containers manually. You can also use `conda` to install the FlexFlow Python package (coming soon).
