+.. _proprietary:
+
+Software X from vendor Y is not compatible with Orthanc
+=======================================================
+
+First of all, make sure to read at least the following sections from
+the :ref:`faq`:
+
+* :ref:`troubleshooting`
+* :ref:`dicom`
+
+Orthanc is `free and open-source software (FOSS)
+<https://en.wikipedia.org/wiki/Free_and_open-source_software>`_. FOSS
+protects the digital freedoms of its users, and is freely available to
+each and every user, for any use. As a backbone application for
+medical imaging, the Orthanc project continuously tries and ensures
+best possible compatibility with other FOSS software. To put it in
+other words, we **provide free support for interfacing Orthanc with
+other free and open-source software**. Feel free to discuss
+interoperability problems of Orthanc with other FOSS tools on `our
+discussion group
+<https://groups.google.com/forum/#!forum/orthanc-users>`_, or to
+introduce `bug reports
+<https://bitbucket.org/sjodogne/orthanc/issues?status=new&status=open>`_
+detailing how to reproduce your problem.
+
+Independently of FOSS, there exist many proprietary systems for
+medical imaging. Note that proprietary systems might either be paying
+or come gratis (also known as freeware). In either case, they restrict
+the freedoms of their users and, as a consequence, the Orthanc project
+does not have access to a valid license for each software X from any
+vendor Y. This implies that we **do not provide free support for
+proprietary software (including freeware)**.
+
+If you encounter difficulties while interfacing Orthanc with some
+proprietary software, **contact the commercial support of your
+supplier**. As Orthanc is free and open-source, the support team of
+your supplier can download Orthanc, and can help you solve your
+problem. If some fix is needed in our source code, the Orthanc project
+will happily integrate it within in the Orthanc mainline, provided the
+**patch is explicitly put in the public domain by your vendor**. We
+remind the vendors that, if they distribute a patched version of
+Orthanc to some of their clients as the result of a commercial
+support, the `GPL license
+<https://en.wikipedia.org/wiki/GNU_General_Public_License>`_ of
+Orthanc requires them to **publicly release the source code of this
+derived version of Orthanc**.
+
+Finally, if you need to complement the commercial services of your
+official supplier, please note that you can also contact a company
+that provides **commercial support on the top of Orthanc**. Currently,
+`Osimis <http://osimis.io/>`_ is the only company ensuring such
+corporate services, but others might show up in the future. A `contact
+form <http://www.orthanc-server.com/orthanc-pro.php>`_ is available on
+the official Web page of Orthanc.
