-
-**Put a short model description here.**
-
-See the [model architecture](#model-architecture) section and [NeMo documentation](https://docs.nvidia.com/deeplearning/nemo/user-guide/docs/en/stable/index.html) for complete architecture details.
-
-
-## NVIDIA NeMo: Training
-
-To train, fine-tune or play with the model you will need to install [NVIDIA NeMo](https://github.com/NVIDIA/NeMo). We recommend you install it after you've installed latest Pytorch version.
-```
-pip install nemo_toolkit['all']
-``` 
-
-## How to Use this Model
+    ## IndicConformer
 
-The model is available for use in the NeMo toolkit [3], and can be used as a pre-trained checkpoint for inference or for fine-tuning on another dataset.
+    IndicConformer is an Hybrid RNNT conformer model built for Urdu.
 
-### Automatically instantiate the model
+    ## AI4Bharat NeMo:
 
-**NOTE**: Please update the model class below to match the class of the model being uploaded.
-
-```python
-import nemo.core import ModelPT
-model = ModelPT.from_pretrained("ai4bharat/indicconformer_stt_ur_hybrid_rnnt_large")
-```
-
-### NOTE
-

-### NOTE
-
-    An example is provided below for ASR
-
-    The NeMo toolkit [3] was used for training the models for over several hundred epochs.
