+# Building TensorFlow and TOCO from source
+
+You can build TensorFlow and tools including `TOCO` from source.
+Please read
+[Installing TensorFlow from Sources](https://www.tensorflow.org/install/install_sources)
+for full description.
+
+## Install Bazel
+
+Follow [Installing Bazel](https://docs.bazel.build/versions/master/install.html)
+- For Ubuntu, follow [Installing Bazel on Ubuntu](https://docs.bazel.build/versions/master/install-ubuntu.html)
+
+These are the actual steps to install using apt package manager:
+```
+sudo apt-get install openjdk-8-jdk
+```
+```
+echo "deb [arch=amd64] http://storage.googleapis.com/bazel-apt stable jdk1.8" \
+| sudo tee /etc/apt/sources.list.d/bazel.list
+curl https://bazel.build/bazel-release.pub.gpg | sudo apt-key add -
+```
+```
+sudo apt-get update && sudo apt-get install bazel
+```
+```
+sudo apt-get upgrade bazel
+```
+
+## Install python packages
+
+```
+sudo apt-get install python-numpy python-dev python-pip python-wheel
+```
+
+## Configure
+
+```
+cd external/tensorflow
+./configure
+```
+
+Select options like this page: https://www.tensorflow.org/install/install_sources#ConfigureInstallation
+
+## Build with Bazel
+
+```
+bazel build --config=opt //tensorflow/tools/pip_package:build_pip_package
+bazel-bin/tensorflow/tools/pip_package/build_pip_package /tmp/tensorflow_pkg
+```
+
+If you have any problems while building, please fire an issue.
+
+## Uninstall if already installed
+
+You may skip this if you haven't installed
+```
+pip uninstall /tmp/tensorflow_pkg/tensorflow-1.6.0rc1-cp27-cp27mu-linux_x86_64.whl
+```
+
+## Install TensorFlow and tools
+
+```
+pip install /tmp/tensorflow_pkg/tensorflow-1.6.0rc1-cp27-cp27mu-linux_x86_64.whl --user
+```
+
+You should see installed `toco` at `~/.local/bin` folder.
