 [T2T](https://github.com/tensorflow/tensor2tensor) is a modular and extensible
-library and binaries for supervised learning with TensorFlow and with a focus on
-sequence tasks. Actively used and maintained by researchers and engineers within
-Google Brain, T2T strives to maximize idea bandwidth and minimize execution
-latency.
-
-T2T is particularly well-suited to researchers working on sequence tasks. We're
-eager to collaborate with you on extending T2T's powers, so please feel free to
-open an issue on GitHub to kick off a discussion and send along pull requests,
-See [our contribution doc](CONTRIBUTING.md) for details and our [open

+Need*](https://arxiv.org/abs/1706.03762) on WMT data.

 pip install tensor2tensor

+## Installation
 
-`t2t-trainer --registry_help`
+```
+pip install tensor2tensor
+```
+
+Binaries:
+
+```
+# Data generator
+t2t-datagen

+t2t-trainer --registry_help
+```
+
+Library usage:
+
+```
+python -c "from tensor2tensor.models.transformer import Transformer"
+```
+
+---
+
+## Features
+
+* Many state of the art and baseline models are built-in and new models can be
+  added easily (open an issue or pull request!).
+* Many datasets across modalities - text, audio, image - available for
+  generation and use, and new ones can be added easily (open an issue or pull
+  request for public datasets!).
+* Models can be used with any dataset and input mode (or even multiple); all
+  modality-specific processing (e.g. embedding lookups for text tokens) is done
+  with `Modality` objects, which are specified per-feature in the dataset/task
+  specification.
+* Support for multi-GPU machines and synchronous (1 master, many workers) and
+  asynchrounous (independent workers synchronizing through a parameter server)
+  distributed training.
+* Easily swap amongst datasets and models by command-line flag with the data
+  generation script `t2t-datagen` and the training script `t2t-trainer`.
