+# Automatic Speech Recognition repository template
+
+This is a template repository for Automatic Speech Recognition to support generic inference with Hugging Face Hub generic Inference API. There are two required steps:
+
+1. Specify the requirements by defining a `requirements.txt` file.
+2. Implement the `pipeline.py` `__init__` and `__call__` methods. These methods are called by the Inference API. The `__init__` method should load the model and preload all the elements needed for inference (model, processors, tokenizers, etc.). This is only called once. The `__call__` method performs the actual inference. Make sure to follow the same input/output specifications defined in the template for the pipeline to work.
+
+Example repos
+* https://huggingface.co/osanseviero/pyctcdecode_asr
+
+## How to start
+First create a repo in https://hf.co/new. 
+Then clone this template and push it to your repo.
+```
+git clone https://huggingface.co/templates/automatic-speech-recognition
+cd automatic-speech-recognition
+git remote set-url origin https://huggingface.co/$YOUR_USER/$YOUR_REPO_NAME
+git push --force
+```
