12**TensorFlow** is an open source software library for numerical computation using
13data flow graphs.  The graph nodes represent mathematical operations, while
14the graph edges represent the multidimensional data arrays (tensors) that flow
15between them.  This flexible architecture lets you deploy computation to one
16or more CPUs or GPUs in a desktop, server, or mobile device without rewriting
17code.  TensorFlow also includes TensorBoard, a data visualization toolkit.
18
19TensorFlow was originally developed by researchers and engineers
20working on the Google Brain team within Google's Machine Intelligence Research
21organization for the purposes of conducting machine learning and deep neural
22networks research.  The system is general enough to be applicable in a wide
23variety of other domains, as well.

25## Installation
26*See [Installing TensorFlow](https://www.tensorflow.org/get_started/os_setup.html) for instructions on how to install our release binaries or how to build from source.*
27
28People who are a little more adventurous can also try our nightly binaries:
29
30**Nightly pip packages**
31* We are pleased to announce that TensorFlow now offers nightly pip packages
32under the [tf-nightly](https://pypi.python.org/pypi/tf-nightly) and
33[tf-nightly-gpu](https://pypi.python.org/pypi/tf-nightly-gpu) project on pypi.
34Simply run `pip install tf-nightly` or `pip install tf-nightly-gpu` in a clean
35environment to install the nightly TensorFlow build. We support CPU and GPU
36packages on Linux, Mac, and Windows.
