 ## export
 Model preparation codes are in _export_ folder. The main entry point is the _LLMEdgeManager_ class. It hosts a _torch.nn.Module_, with a list of methods that can be used to prepare the LLM model for ExecuTorch runtime.
-Note that ExecuTorch supports two [quantization APIs](https://pytorch.org/docs/stable/quantization.html#quantization-api-summary): eager mode quantization (aka source transform based quantization), and PyTorch 2 Export based quantization (aka pt2e quantization).
-Typical methods include:

 A sampler class in C++ to sample the logistics given some hyperparameters.
 
 ## custom_ops
-It hosts a custom sdpa operator. This sdpa operator implements CPU flash attention, it avoids copies by taking the kv cache as one of the arguments to this custom operator.

 ## runner
 It hosts the libary components used in a C++ llm runner. Currently, it hosts _stats.h_ on runtime status like token numbers and latency.
 
-With the components above, an actual runner can be built for a model or a series of models. An exmaple is in //executorch/examples/models/llama2/runner, where a C++ runner code is built to run Llama 2, 3, 3.1 and other models using the same architecture.
