+Overview
+========
+
+.. note::
+
+	PDFmorph is currently run from the command line, which requires
+	opening and typing into a terminal window or Windows command
+	prompt. It is recommended that you consult online resources and
+	become somewhat familiar before using PDFmorph.
+
+PDFmorph is a Python software package designed to increase the insight
+researchers can obtain from measured atomic pair distribution functions
+(PDFs) in a model-independent way. The program was designed to help a
+researcher answer the question: "Has my material undergone a phase
+transition between these two measurements?"
+
+PDFmorph makes use of several data manipulation techniques to correct
+for benign effects such as thermal expansion (peak shift) and increased
+thermal motion (peak broadening) or a change in scale due to differences
+in incident flux, for example. PDFmorph will do its best to correct
+for these benign effects before computing and plotting a difference
+curve.
+
+One PDF (typically that collected at higher temperature) is identified
+as the "target" PDF and the second is "morphed" by "stretching" (changing
+the r-axis to simulate a uniform lattice expansion), "smearing"
+(broadening peaks through a uniform convolution to simulate increased
+thermal motion), and "scaling" (self-explanatory). PDFmorph will vary
+amplitude of morphing transformations to obtain the best fit between
+morphed and target PDFs, then plot them along with the difference curve
+plotted below.
+
+There are also a few other morphing transformations in the program.
+
+Finally, we note that PDFmorph should work on other spectra that are
+not PDFs, though it has not been extensively tested beyond the PDF.
+
+.. PDFmorph will soon be included in :doc:`xPDFsuite <xPDFsuite>`, a powerful end-to-end software for X-ray PDF analysis. xPDFsuite is designed for flexible, high throughput PDF analyses and contains many features for interrogating, comparing, and modeling data as well as simply doing data reduction.

+Installation
+============
+
+By downloading and using this software, you are agreeing to the conditions
+specified in the software :doc:`LICENSE <pdfmorph_license>`.
+
+PDFmorph will run on Python 3.5 or higher or on Python 2.7.
+We recommend to use Anaconda Python which can be obtained from
+|anaconda-download|.
+PDFmorph is available from the ``diffpy`` channel of Anaconda
+packages and also from `conda-forge <https://conda-forge.org>`__.
+To install open a *Terminal* window (*Anaconda Command Prompt*
+on Windows) and use the :program:`conda` command as follows ::
+
+   conda install --channel=diffpy diffpy.pdfmorph
+
+If you prefer to use ``conda-forge`` make sure it is configured as
+the priority channel for Anaconda packages, which will allow you
+to install without the ``--channel`` option ::
+
+   conda config --add channels conda-forge
+   conda install diffpy.pdfmorph
+
+For all other Python distributions use the standard
+:program:`pip` installation program::
+
+   pip install diffpy.pdfmorph
+
+To make sure that the installation has completed correctly,
+run the following command from a *Terminal* ::
+
+   pdfmorph --version
+
+If all is good this should display the version of PDFmorph installed on your
+machine.
+
+
+PDFmorph Updates
+================
+
+The Anaconda package system makes it easy to prepare and distribute
+software packages and bugfixes. To obtain the latest version of PDFmorph,
+use ::
+
+	conda update diffpy.pdfmorph
+
+With other Python distributions, the program can be updated to the
+latest version with ::
+
+	pip --upgrade diffpy.pdfmorph
+
+To use a development version, visit the project source repository
+https://github.com/diffpy/diffpy.pdfmorph and consult its README file.
