-This repository contains the code for the domain classifier model.
+# Model Overview
+This is a text classification model to classify documents into one of 26 domain classes:
+
+'Adult', 'Arts_and_Entertainment', 'Autos_and_Vehicles', 'Beauty_and_Fitness', 'Books_and_Literature', 'Business_and_Industrial', 'Computers_and_Electronics', 'Finance', 'Food_and_Drink', 'Games', 'Health', 'Hobbies_and_Leisure', 'Home_and_Garden', 'Internet_and_Telecom', 'Jobs_and_Education', 'Law_and_Government', 'News', 'Online_Communities', 'People_and_Society', 'Pets_and_Animals', 'Real_Estate', 'Science', 'Sensitive_Subjects', 'Shopping', 'Sports', 'Travel_and_Transportation'
+# Model Architecture
+The model architecture is Deberta V3 Base
+Context length is 512 tokens
+# Training (details)
+## Training data:
+- 1 million Common Crawl samples, labeled using Google Cloud’s Natural Language API: https://cloud.google.com/natural-language/docs/classifying-text
+- 500k Wikepedia articles, curated using Wikipedia-API: https://pypi.org/project/Wikipedia-API/
+## Training steps:
+Model was trained in multiple rounds using Wikipedia and Common Crawl data, labeled by a combination of pseudo labels and Google Cloud API.
+# How To Use This Model
+## Input
+The model takes one or several paragraphs of text as input.
+Example input:
+```
+q Directions
+1. Mix 2 flours and baking powder together
+2. Mix water and egg in a separate bowl. Add dry to wet little by little
+3. Heat frying pan on medium
+4. Pour batter into pan and then put blueberries on top before flipping
+5. Top with desired toppings!
+```
+## Output
+The model outputs one of the 26 domain classes as the predicted domain for each input sample.
+Example output:
+```
+Food_and_Drink
+```
+
+# How to use in NeMo Curator
+
+The inference code is available on NeMo Curator's GitHub repository. Download the [model.pth](https://huggingface.co/nvidia/domain-classifier/blob/main/model.pth) file and check out this [example notebook](https://github.com/NVIDIA/NeMo-Curator/blob/main/tutorials/distributed_data_classification/distributed_data_classification.ipynb) to get started.
 
 # How to use in transformers
 To use the Domain classifier, use the following code:
 
-```python3
+```python
 
 import torch
 from torch import nn
@@ -45,4 +80,46 @@ predicted_classes = torch.argmax(outputs, dim=1)
 predicted_domains = [config.id2label[class_idx.item()] for class_idx in predicted_classes.cpu().numpy()]
 print(predicted_domains)
 # ['Sports', 'News']

+# Evaluation Benchmarks
+
+Evaluation Metric: PR-AUC
+PR-AUC score on evaluation set with 105k samples - 0.9873 
+PR-AUC score for each domain:
