+Manual Installation (Dev Setup)
+--------------------------------
+
+To setup Lux manually for development purposes, you should clone the two Github repos for Lux: 1) the core Python `Lux API <https://github.com/lux-org/lux>`_  and 2) the `Jupyter widget frontend <https://github.com/lux-org/lux-widget>`_. 
+
+To install the Python Lux API: 
+
+.. code-block:: console
+
+    pip install --user -r requirements.txt
+    cd lux/
+    python setup.py install
+
+To install the widget, we need to install webpack:  
+
+.. code-block:: console
+    
+    npm install --save-dev webpack webpack-cli
+
+Then, we can install the `Lux Jupyter widget <https://github.com/lux-org/lux-widget>`_ using the custom installation script: 
+
+.. code-block:: console
+
+    git clone git@github.com:lux-org/lux-widget.git
+    cd lux-widget/
+    npm install
+    bash install.sh
+
+If you are experiencing issues with installing Lux, please checkout the `Troubleshooting page <https://lux-api.readthedocs.io/en/latest/source/guide/FAQ.html#troubleshooting-tips>`_.
