+Quantum transport simulations made easy
+=======================================
+
+Kwant is a `free (open source) <https://gitlab.kwant-project.org/kwant/kwant>`_ Python
+package for numerical calculations on tight-binding models with a strong focus
+on quantum transport.  It is designed to be flexible and easy to use.  Thanks to
+the use of innovative algorithms, Kwant is often faster than other available
+codes, even those entirely written in the low level FORTRAN and C/C++ languages.
+
+Tight-binding models can describe a vast variety of systems and phenomena in
+quantum physics.  Therefore, Kwant can be used to simulate metals, graphene,
+topological insulators, quantum Hall effect, superconductivity, spintronics,
+molecular electronics, any combination of the above, and many other things.
+
+Kwant does not use the traditional input files often found in scientific
+software packages. Instead, one writes short programs in the powerful yet
+easy-to-learn Python language.  These programs define a system and calculate its
+quantum properties (conductance, density of states, etc).  This workflow can be
+summarized as follows:
+
+.. raw:: html
+
+    <object type="image/svg+xml" data="kwant-workflow.svgz" class="img-responsive">kwant-workflow.svgz</object>
+
+Kwant was designed to be easy to use: Section 2 of the `Kwant paper
+<http://downloads.kwant-project.org/doc/kwant-paper.pdf>`_ contains a
+line-by-line walkthrough of a program very similar to the one used to generate
+the above image.  That complete Python script is 26 lines long (including
+comments).
+
+
+Examples of Kwant usage
+-----------------------
+
+The following examples are meant to give an overview of what is possible with
+Kwant.  The tutorial section of `Kwant documentation <doc/1/>`_ and the
+`Kwant paper`_ each contain several pedagogical examples with line-by-line
+explanations (`zipfile of all examples
+<http://downloads.kwant-project.org/examples/kwant-examples-1.0.0.zip>`_).
+
+Graphene flake
+..............
+
+.. raw:: html
+
+       <object type="image/svg+xml" class="col-md-4 pull-left img-responsive" data="graphene-edgestate.svgz">graphene-edgestate.svgz</object>
+
+The complete code that constructs the graphene flake shown on the right side is
+
+.. code:: python
+
+          def disk(pos):
+              x, y = pos
+              return x**2 + y**2 < 8**2
+
+          lat = kwant.lattice.honeycomb()
+          syst = kwant.Builder()
+          syst[lat.shape(disk, (0, 0))] = 0
+          syst[lat.neighbors()] = -1
+
+In addition to the flake itself, the image also shows the wave function of a
+low energy eigenstate. The size of each circle is proportional to the wave
+function probability amplitude on that site.  It can be clearly seen that the
+wave function is peaked near the zigzag segments of the boundary, as `expected
+<http://arxiv.org/abs/1003.4602>`_ for graphene quantum dots.
+
+Taken from the Kwant `plotting tutorial <doc/1/tutorial/tutorial6.html>`_.

+
+Quantum Hall effect
+...................
+
+.. raw:: html
+
+       <object type="image/svg+xml" class="col-md-4 img-responsive pull-left" data="qhe-edgestate.svgz">qhe-edgestate.svgz</object>
+
+       <object type="image/svg+xml" class="col-md-4 img-responsive pull-right" data="qhe-plateaus.svgz">qhe-plateaus.svgz</object>
+
+
+One of the most common applications of Kwant is to calculate the conductance of
+a nanoelectronic system.  The plot on the left shows the conductance through a
+2-d electron gas as a function of magnetic flux.  The quantization of
+conductance that is visible (plateaus) is the hallmark of the quantum Hall
+effect.  The third plateau does not develop due to a constriction in the system
+that leads to backscattering.  The scattering wave function from the left lead
+at magnetic field strength corresponding to the middle of the third QHE plateau
+is shown on the right.
+
+Taken from example 6 of the `Kwant paper
+<http://downloads.kwant-project.org/doc/kwant-paper.pdf>`_.

+3-d system: Majorana states
+...........................
+
+.. class:: col-md-4 img-responsive pull-left
+
+.. image:: quantum-wire.png
+
+Kwant allows systems of any dimensionality, for example three-dimensional ones.
+This image shows a 3-d model of a semiconducting quantum wire (gray cylinder).
+The red region is a tunnel barrier, used to measure tunneling conductance, the
+blue region is a superconducting electrode.  In this simulated device, a
+Majorana bound state appears close to the superconducting-normal interface.

+
+Numerical simulations and experimental results for a flying qubit sample made in
+a GaAs/GaAlAs heterostrucutre. The Kwant simulations were performed with
+particular attention to a realistic model of the confining potential seen by the
+electrons.  This allows for rather subtle aspects of the experiment could be
+reproduced.  Such "numerical experiments" can not only be used to interpret the
+experimental data but also can help to design the sample geometry and in to
+choose the right materials.
+
+Taken from an unpublished work by T. Bautze et al.  See Yamamoto et al., `Nature
+Nanotechnology 7, 247 (2012) <http://dx.doi.org/doi:10.1038/nnano.2012.28>`_ for
+details about the experiment.

+The Kwant community
+===================
+
+The Kwant project is an international collaboration.
+Everybody is welcome to participate in the community
+by asking and replying to questions, reporting bugs, providing suggestions,
+and `contributing to the code and documentation </contribute.html>`_.
+
+The Kwant community uses three public communication channels:
+the mailing list for generic discussions, questions, and announcements;
+the gitlab instance for development discussions and reporting bugs;
+and the chat for real-time discussions related to development.
+
+A list of `Kwant authors </authors>`_ is included in the documentation.
+Please contact the authors directly only for matters that cannot be discussed on the public channels.
+
+
+Mailing list
+------------
+
+The kwant-discuss mailing list is the main public communication platform for anything related to Kwant:
+questions, discussions, development, and announcements.
+It may be used both as a web forum and as a classical mailing list.
+
+The `kwant-discuss web interface <https://mail.python.org/archives/list/kwant-discuss@python.org/>`_
+allows to follow discussions and search the archives.
+
+To start a new discussion thread, you may either use the web interface
+(sign-in required)
+or write directly to
+kwant-discuss@python.org.
+In order to avoid spam,
+messages of unsubscribed participants are held for moderation.
+
+Similarly, replying is possible either by mail
+(if you received the post to which you want reply by mail),
+or using the web interface:
+the “reply” button under each message allows to compose directly
+(for signed-in users),
+or triggers a reply by mail (otherwise).
+
+You may subscribe to receive posts to the list by mail.
+Subscription is done either through the
+`kwant-discuss info page
+<https://mail.python.org/mailman3/lists/kwant-discuss.python.org/>`_
+or by sending any message to
+kwant-discuss-join@python.org.
+(The subject and content are ignored and may be empty.)
+To unsubscribe, either use the info page,
+or send any message to kwant-discuss-leave@python.org.
+
+List etiquette :
+
+- When asking questions,
+  `help others to help you <https://stackoverflow.com/help/how-to-ask>`_.
+  In particular, use the search function before posting.
+
+- When replying, please avoid quoting the complete original message.
+  Instead, consider
+  `bottom-posting <https://en.wikipedia.org/wiki/Posting_style#Bottom-posting>`_.
+
+
+Announcements mailing list
+--------------------------
+
+This read-only list is used for important announcements like new releases of Kwant.
+Only a few messages are sent per year.
+These announcements are also posted on the main mailing list,
+so there is no need to subscribe to both lists.
+We recommend every user of Kwant to subscribe at least to this list in order to stay informed about new developments.
+
+The `kwant-announce archives <https://mail.python.org/archives/list/kwant-announce@python.org/>`_
+are available on the web.
+
+To subscribe, either use the form on the `kwant-announce info page <https://mail.python.org/mailman3/lists/kwant-announce.python.org/>`_

+The Kwant developer chat is accessible to the community via `Gitter <https://gitter.im/kwant-project/Lobby>`_.
+Come say hi if you would like to get involved with developing Kwant!
+
+
+Gitlab instance
+---------------
+
+The Kwant project runs a `gitlab instance <https://gitlab.kwant-project.org/>`_
+that hosts the `main Kwant code repository <https://gitlab.kwant-project.org/kwant/kwant>`_
+as well as the `repositories of related projects <https://gitlab.kwant-project.org/kwant>`_.
+The gitlab instance is used for reporting bugs (see next section) and `development </contribute.html>`_
+
+
+Reporting bugs
+--------------
+
+If you encounter a problem with Kwant,
+first try to reproduce it with as simple a system as possible.
+Double-check with the documentation that what you observe is actually a bug in Kwant.
+If you think it is, please check `the list of known bugs in Kwant <https://gitlab.kwant-project.org/kwant/kwant/issues?label_name=bug>`_.
+It may be also a good idea to search or ask on the general mailing list.
+(You can use the search box at the top of this page.)
+
+If after checking you still think that you have found a bug, please add it to
+the above-mentioned list of bugs by creating an issue with the “bug” label.  A
+useful bug report should contain:
+
+- The versions of software you are using: Kwant, Python, operating system, etc.
+
+- A description of the problem, i.e. what exactly goes wrong.  This should
+  include any relevant error messages.
+
+- Enough information to reproduce the bug, preferably in the form of a simple
+  script.

+Contributing to Kwant
+=====================
+
+We see Kwant not just as a package with fixed functionality, but rather as a
+framework for implementing different physics-related algorithms using a common
+set of concepts.  Contributions to Kwant are highly welcome.  You can help the
+project not only by writing code, but also by reporting bugs, and
+fixing/improving the website and the documentation.
+
+
+Where help is needed
+--------------------
+
+The `Kwant issue tracker
+<https://gitlab.kwant-project.org/kwant/kwant/issues>`_ serves to track bugs
+in Kwant, but most issues are in fact ideas for enhancements.  The issues are
+categorized with labels, so that it is possible to view `all the “easy” issues
+<https://gitlab.kwant-project.org/kwant/kwant/issues?label_name=difficulty%3A+easy>`_
+for example.
+
+Please do feel free to enter new issues yourself.  If you are unsure about some aspect It may be a good idea to discuss your idea on the mailing list kwant-discuss@kwant-project.org before filing an issue.
+
+If you already have some code that extends Kwant in a useful way, please
+consider sharing it.  If your extension fits well with Kwant and is of wide
+enough interest, we will be happy to include it into Kwant proper.  For more
+specialized cases, we will find a solution as well.  (We could, for example,
+add a list of Kwant-related modules to this website.)  In any case, external
+contributions will be clearly marked as such, and relevant papers will be
+added to the list of `suggested acknowledgements </cite.html>`_.
+
+
+Getting the source code
+-----------------------
+
+The source code of released versions of Kwant is available for `download
+<http://downloads.kwant-project.org/kwant/>`_.  You can follow the development
+through the `Kwant page of our GitLab instance
+<https://gitlab.kwant-project.org/kwant/kwant>`_.  The `Git
+<http://git-scm.com/>`_ repository of Kwant can be cloned directly with the
+command ::
+
+    git clone https://gitlab.kwant-project.org/kwant/kwant.git
+
+The Kwant git repository has two main branches: The branch *master*
+contains the development towards the next release.  The branch *stable* contains
+the most recent release that is considered stable, and only bugfixes are applied
+to it.
+
+
+Setting up for development
+--------------------------
+
+When working with the Kwant source, regular `build instructions
+</doc/1/pre/install.html#building-and-installing-from-source>`_ apply.  It
+would be tiresome, however, to have to reinstall the modified Kwant after each
+modification.
+
+One easy way to avoid this is to build in-place so that there is no need to
+reinstall after each change.  This can be done with the following command ::
+
+    python3 setup.py build_ext -i
+
+No further installation is necessary.  The “inner” ``kwant`` subdirectory has
+been turned into a proper Python package that can be imported from the “outer”
+directory, i.e. the directory where ``setup.py`` is located.  Any script
+inside that directory that imports Kwant will get the modified version.  (To
+be able to import the modified Kwant from another directory one can create a
+symbolic link to the package.)
+
+The above ``build_ext`` command does not have to be rerun when a Python file
+is modified.  Recompilation is only necessary whenever a Cython file
+(``.pyx``) has been changed.
+
+
+Modifying the source code
+-------------------------
+
+We recommend that you keep each of your changes to Kwant on a separate “topic
+branch” that starts at *master*.  Try to not mix up unrelated changes in a
+single branch.  To create a topic branch, use the command::
+
+    git checkout -b my_topic master
+
+Now you can begin to implement your idea.  As you go, register your changes
+with Git as explained, for example, in the `Pro Git book
+<https://git-scm.com/book/en/v2/Git-Basics-Recording-Changes-to-the-Repository>`_
+that is freely available online.
+
+Once you feel that you would like to show your work to other interested people
+(because you would like to receive feedback, or because you consider it
+ready), it's time to inspect your branch.  Run ``git status`` to make sure
+that you have committed all of your changes, then use a tool like ``gitk`` to
+view your branch.
+
+In the following, two methods to share your commits are described.  The first
+will be familiar if you have experience with the popular GitHub service.  If
+you do not, you might prefer the second method, since it is simpler.
+
+
+Method 1: Using the Kwant GitLab instance
+.........................................
+
+Go the `GitLab page of the official Kwant repository
+<https://gitlab.kwant-project.org/kwant/kwant>`_.  Since you do not have write
+access to this repository, you have to create an own “fork” of it by clicking
+on the button just right of the “star” button.
+
+You created a public copy of the Kwant repository that is controlled by you.
+Add it as a remote repository to the clone of Kwant on your computer::
+
+    git remote add own https://gitlab.kwant-project.org/<USERNAME>/kwant.git
+
+You can copy-and-paste your own version of the above URL from the main page of
+your repository.  (If you know about SSH, you may also prefer to upload your
+public ssh key to GitLab and to use SSH as transport.)  The string ``own`` is
+the local name you give to the remote, it can be anything.
+
+Now you can push your topic branch to your repository::
+
+    git push own my_branch
+
+This will make your branch appear in GitLab.  Now you can let us know about
+your branch by `creating a merge request in GitLab
+<https://gitlab.kwant-project.org/help/workflow/forking_workflow.md>`_ or by
+sending a message to kwant-discuss@kwant-project.org.
+
+
+Method 2: Sending patches to the mailing list
+.............................................
+
+Run the command ::
+
+    git format-patch origin/master
+
+This will create a “patch” file for each commit on your branch.  Now simply
+send these patches as email attachments to kwant-discuss@kwant-project.org,
+together with an explanation of your idea.  You do not have to be subscribed
+to the mailing list.
+
+(Or, even better, use ``git send-email`` as shown in this `example of usage
+<https://kernel.org/pub/software/scm/git/docs/git-send-email.html#_example>`_
+and this `git send-email howto
+<http://www.freedesktop.org/wiki/Software/PulseAudio/HowToUseGitSendEmail/>`_.)
+
+
+Coding style
+------------
+
+* Please keep the code consistent by adhering to the prevailing naming and
+  formatting conventions.  We generally respect the `"Style Guide for Python
+  Code" <http://www.python.org/dev/peps/pep-0008/>`_.  For docstrings, we
+  follow `NumPy's "Docstring Standard"
+  <http://github.com/numpy/numpy/blob/master/doc/HOWTO_DOCUMENT.rst.txt>`_ and
+  `Python's "Docstring Conventions"
+  <http://www.python.org/dev/peps/pep-0257/>`_.
+
+* Write tests for all the important functionality you add.  Be sure not to
+  break existing tests.
+
+* Create a logical sequence of commits with clear commit messages.  Each
+  commit message consists of a summary line, and, whenever necessary, a
+  more detailed explanation.  Both parts are separated by a blank line
+  and wrapped to 72 characters (unless quoting error messages and such).
+  The summary line should be as clear as possible.  The detailed
+  explanation should be included whenever it helps to motivate or
+  understand the commit.  Bear in mind that the merge request text and
+  discussions are not part of a commit.

-Numerics of tight binding models made easy
-==========================================
-
-kwant is a Python package for numerical calculations on tigh-binding models
-with most focus on quantum transport.  It is designed to be flexible, easy to
-use, while not sacrificing performance.
-
-Its flexbility is illustrated below by showcasing some of its applications. How
-easy it is to use is shown in the tutorial, and finally its performance was
-carefully tested.
-
-.. image:: collage.png
-   :scale: 30%
-
-Image: various applications of kwant:
-
-* conductance of a Corbino disk in a quantum Hall regime
-* A piece of bilayer graphene lattice
-* Density of states in a chaotic stadium billiard
-* A quantum wire with a proximity superconductor, and the Majorana states
-  in its spectrum.
