+   You can adapt this file completely to your liking, but it should at least
+   contain the root `toctree` directive.

+.. _installation:
+
+===========================
+Installation
+===========================
+
+You must first have a working and properly configured Python 3.4+ distribution
+on your computer. We often use and highly recommend
+`Anaconda <https://www.anaconda.com/download/>`_.
+
+Simple user
+------------
+
+If you have other Python programs besides PyWake, it is a good idea to install
+each program in its own environment to ensure that the dependencies for the
+different packages do not conflict with one another. The commands to create and
+then activate an environment in an Anaconda prompt are::
+
+   conda create --name pywake python=3.6
+   activate pywake
+
+You can install PyWake into the current active environment directly from git::
+
+   pip install git+https://gitlab.windenergy.dtu.dk/TOPFARM/PyWake.git
+
+
+Developer
+----------
+
+We highly recommend developers install PyWake into its own environment. (See
+instructions above.) The commands to clone and install PyWake with developer
+options into the current active environment in an Anaconda Prommpt are as
+follows::
+
+   git clone https://gitlab.windenergy.dtu.dk/TOPFARM/PyWake.git
+   cd PyWake
+   pip install -e .
