 ## Overview
-RETVec is a next-gen text vectorizer designed to offer built-in adversarial resilience using robust word embeddings. Read the paper here: https://arxiv.org/abs/2302.09207.
+RETVec is a next-gen text vectorizer designed to be efficient, multilingual, and provide built-in adversarial resilience using robust word embeddings trained with [similarity learning](https://github.com/tensorflow/similarity/). You can read the paper [here](https://arxiv.org/abs/2302.09207).
 
-RETVec is trained to be resilient against character manipulations including insertion, deletion, typos, homoglyphs, LEET substitution, and more. The RETVec model is trained on top of a novel character embedding which can encode all UTF-8 characters and words. Thus, RETVec works out-of-the-box on over 100 languages without the need for a lookup table or fixed vocabulary size. Furthermore, RETVec is a layer, which means that it can be inserted into any TF model without the need for a separate pre-processing step.

+RETVec's speed and size (~200k instead of millions) also makes it a great choice for on-device and web use cases. It is natively supported in TensorFlow Lite via custom ops implemented in TensorFlow Text, and we provide a Javascript implementation of RETVec which allows you to deploy web models via TensorFlow.js.

 ### Basic Usage
 
-`training/train_tf_retvec_models.py` is the RETVec model training script. Example usage:
+You can use RETVec as the vectorization layer in any TensorFlow model with just a single line of code. RETVec operates on raw strings with pre-processing options built-in (e.g. lowercasing text). For example:
 
-```python
-train_tf_retvec_models.py --train_config <train_config_path> --model_config <model_config_path> --output_dir <output_path>
 ```
+import tensorflow as tf
+from tensorflow.keras import layers
+
+# Define the input layer, which accepts raw strings
+inputs = layers.Input(shape=(1, ), name="input", dtype=tf.string)
+
+# Add the RETVec Tokenizer layer using the RETVec embedding model -- that's it!
+x = RETVecTokenizer(sequence_length=128)(inputs)
+
+# Create your model like normal
+# e.g. a simple LSTM model for classification with NUM_CLASSES classes
+x = layers.Bidirectional(layers.LSTM(64, return_sequences=True))(x)
+x = layers.Bidirectional(layers.LSTM(64))(x)
+outputs = layers.Dense(NUM_CLASSES, activation='softmax')(x)
+model = tf.keras.Model(inputs, outputs)
+```
+
+Then you can compile, train and save your model like usual! As demonstrated in our paper, models trained using RETVec are more resilient against adversarial attacks and typos, as well as computationally efficient. RETVec also offers support in TFJS and TF Lite, making it perfect for on-device mobile and web use cases.

+### Colabs
 
-Configurations for our base models are under the `configs/` folder.
+Detailed example colabs for RETVec can be found at under [notebooks](notebooks/). These are a good way to get started with using RETVec. You can run the notebooks in Google Colab by clicking the Google Colab button. If none of the examples are similar to your use case, please let us know!
