+Installation
+~~~~~~~~~~~~
+
+ACT can be installed a few different ways. One way is to install using pip.
+When installing with pip, the ACT dependencies found in
+`requirements.txt <https://github.com/ANL-DIGR/ACT/blob/master/requirements.txt>`_ will also be installed. To install using pip::
+
+    pip install act-atmos
+
+The easiest method for installing ACT is to use the conda packages from
+the latest release. To do this you must download and install 
+`Anaconda <https://www.anaconda.com/download/#>`_ or 
+`Miniconda <https://conda.io/miniconda.html>`_.
+With Anaconda or Miniconda install, it is recommended to create a new conda
+environment when using ACT or even other packages. To create a new
+environment based on the `environment.yml <https://github.com/ANL-DIGR/ACT/blob/master/environment.yml>`_::
+
+    conda env create -f environment.yml
+
+Or for a basic environment and downloading optional dependencies as needed::
+
+    conda create -n act_env -c conda-forge python=3.7 act-atmos
+
+Basic command in a terminal or command prompt to install the latest version of
+ACT::
+
+    conda install -c conda-forge act-atmos
+
+To update an older version of ACT to the latest release use::
+
+    conda update -c conda-forge act-atmos
+
+If you do not wish to use Anaconda or Miniconda as a Python environment or want
+to use the latest, unreleased version of ACT see the section below on 
+**Installing from source**.
