+Development Setup
+=================
+
+Assuming that you are on ubuntu 16.04, with nvidia-drivers installed.
+
+In bash, source the ``path.bash.inc`` script.  This will install a
+local conda environment under ``./.dev_env``, which includes pytorch
+and some dependencies (no root required).
+
+.. code:: bash
+
+   source ./path.bash.inc
+   python -c "import torchgeometry; print(torchgeometry.__version__)"
+
+
+
+To install, or update the conda environment run ``setup_dev_env.sh``
+
+.. code:: bash
+
+   ./setup_dev_env.sh
+
+
