+
+Dockerized development
+======================
+
+If you have Docker available on your platform, you can get started building CSS and JS artifacts a bit faster and won't have to worry about any of the setup spilling over into your general environment.
+
+When building with Docker, we create an image containing the build dependencies. Some of these are quite outdated and therefore ideal to isolate a container. The image is tagged as ``sphinx_rtd_theme:latest``.
+
+Inside the running docker image, we mount the working copy of the repository, build the artifacts and finally observe that the artifacts have been built and left in your current git checkout.
+
+Use the following steps:
+
+.. code-block:: console
+
+    # Builds an updated version of the docker image
+    $ docker-compose build
+
+    # Runs the development webserver
+    $ docker-compose run sphinx_rtd_theme dev
+    
+    # If you want to copy stuff out of the Docker environment, run this make
+    # target or read the actual Makefile to see what is going on.
+    # We suggest running this command every time that you want to quickly build
+    # new CSS/JS assets
+    $ make docker-build-all
+
+Every time you change the Node or Python requirements, you will need to rebuild images with ``docker-compose run sphinx_rtd_theme build``. If you change SASS or JS, you will need to rebuild assets.
+
+Testing
+=======
+
+QA testing theme changes and pull requests is complex, due to backwards
+compatibility.
+
+The following cases need to be tested with changes to CSS or JavaScript:
+
+* Multiple, modern browsers should be tested. We officially support back
+  to IE11 at the moment
+* Multiple viewport sizes should be tested for changes. We support large,
+  tablet, and mobile viewport sizes
+* We currently support both the Sphinx HTML4 writer and HTML5 writer. This makes
+  for some complex CSS selectors
+* Multiple major versions of Sphinx should be tested. We currently support back
+  to Sphinx version ``1.6``
+
+It's easiest to test combinations of dependency versions using ``tox``:
+
+.. code:: console
+
+    % tox -e py3-sphinx34-html4
+
+If the tests and build are successful, you can view the built documentation at
+the directory noted by Sphinx:
+
+.. code:: console
+
+    build succeeded, 10 warnings.
+
+    The HTML pages are in .tox/py3-sphinx34-html4/tmp/html.
+    ___________________________ summary ___________________________
+      py3-sphinx34-html4: commands succeeded
+      congratulations :)
+
+You can then open up this path with a series of browsers to test.
+
+The best way to spot UI issues is to compare two or more builds. You can build
+multiple ``tox`` environments, and open both up for comparison:
+
+.. code:: console
+
+    % tox -e py3-sphinx34-html4
+    ...
+    % tox -e py3-sphinx34-html5
+    ...
+    % firefox .tox/py3-sphinx34-html4/tmp/html/index.html
+    % firefox .tox/py3-sphinx34-html5/tmp/html/index.html
+
+You can also use a separate ``tox`` environment for building output to compare
+against. All of the ``tox`` environments have an additional postfix, ``-qa``, to
+allow building the same environment twice, without overwriting any files. In
+this test scenario, you would build from a branch or tag before building the
+same ``tox`` environment for the pull request branch you are testing.
+
+For example, to test against the tag ``0.5.2``:
+
+.. code:: console
+
+    % git checkout 0.5.2
+    % tox -e py3-sphinx34-html4-qa
+    ...
+    % git checkout feature/example-pull-request
+    % tox -e py3-sphinx34-html4
+    ...
+    % firefox .tox/py3-sphinx34-html4-qa/tmp/html/index.html
+    % firefox .tox/py3-sphinx34-html4/tmp/html/index.html
+
+Currently, the most important environments to QA are:
+
+.. This list is purposely shorter than what we describe above. If we test all of
+   the cases above, we'll be here all day. Python 3, HTML4/5 writer, and latest
+   minor of each major Sphinx release should give us enough work.
+
+* ``py3-sphinx18-html4``
+* ``py3-sphinx18-html5``

+Development
+===========
+
+The theme developers follow the guidelines below for development and release
+planning. Documentation authors can decide which theme release works best for
+their project based on required browser/operating system combinations or
+dependency support.
+
+.. _supported-browsers:
+
+Supported browsers
+------------------
+
+Official browser support is determined by the most popular browser/operating
+system combinations in our pageview analytics. Officially supported combinations
+are commonly tested during development, and are always tested before final
+release of a new version of the theme.
+
+Older releases of supported combinations, and some less common combinations, are
+considered partially supported. This means that we do not consistently test
+these combinations, however we do expect user experience to be comparable with
+supported combinations.
+
+.. csv-table:: Supported browser combinations
+    :widths: 6, 12, 4
+    :header-rows: 1
+    :file: supported-browsers.csv
+
+.. versionadded:: 1.0
+    Supported browser and operating system combinations added
+
+There are several browser/operating system combinations that are not supported
+by the theme developers at all. Unsupported combinations do not receive testing
+or development, and we likely won't accept major contributions for these
+combinations.
+
+Unsupported browser/operating system combinations include:
+
+Internet Explorer (any OS, versions <=10)
+    **Unsupported.** IE11 is the last partially supported version. We do no
+    testing on prior versions.
+
+Internet Explorer (any OS, version 11)
+    We currently only partially support IE11, and only test for major bugs.
+    Support will be removed in the :ref:`2.0.0` release.
+
+Opera (any OS, any version)
+    **Community support only.** We do not receive enough traffic with this
+    browser to officially support it in testing and development.
+
+.. _supported-dependencies:
+
+Supported dependencies
+----------------------
+
+The theme officially supports the following dependencies in your Sphinx project:

+
+Roadmap
+-------
+
+We currently have several releases planned on our development roadmap. Backward
+incompatible changes, deprecations, and major features are noted for each of
+these releases.
+
+Releases follow `semantic versioning`_, and so it is generally recommended that
+authors pin dependency on ``sphinx_rtd_theme`` to a version below the next major
+version:
+
+.. code:: console
+
+    $ pip install "sphinx_rtd_theme<=2.0.0"
+
+.. _semantic versioning: http://semver.org/
+
+.. _release-1.0.0:
+
+1.0.0
+~~~~~
+
+:Planned release date: August 2021
+
+This release will be a slightly backwards incompatible release to follow the
+:ref:`0.5.2` release. It will drop support for Sphinx 1.6, which is a rather old
+release at this point.
+
+This version will add official support for the Sphinx 4.x release series and
+it resolves bugs with the latest release of Docutils, version 0.17.
+
+Starting with this release, several deprecation warnings will be emitted at
+build time:
+
+Direct installation is deprecated
+    Support for direct installation through GitHub is no longer a suggested
+    installation method. In an effort to ease maintenance, compiled assets will
+    eventually be removed from the theme repository. These files will only be
+    included in the built packages/releases available on PyPI.
+
+    We plan to start putting development releases up on PyPI more frequently, so
+    that installation from the theme source repository is no longer necessary.
+
+    Built assets are tentatively planned to be removed in version :ref:`3.0.0`:.
+
+HTML4 support is deprecated
+    Support for the Sphinx HTML4 writer will be removed in the :ref:`2.0.0`
+    release.
+
+.. _release-1.1.0:
+
+1.1.0
+~~~~~
+
+:Planned release date: 2021 Q3
+
+We aim to follow up release :ref:`1.0.0` with at least one bug fix release in
+the 1.x release series. The 1.1 release will not be adding any major features
+and will instead mark the last release targeting projects with old dependencies
+like Sphinx 1.8, HTML4, or required support for IE11.
+
+.. _release-2.0.0:
+
+2.0.0
+~~~~~
+
+:Planned release date: 2022 Q1
+
+This release will mark the beginning of a new round of feature development, as
+well as a number of backward incompatible changes and deprecations.
+
+Of note, the following backwards incompatible changes are planned for this
+release:
+
+Sphinx 1.x, Sphinx 2.x, and Docutils 0.16 will not be tested
+    Official support will drop for these version, though they may still continue
+    to work. Theme developers will not be testing these versions any longer.
+
+HTML4 support will be removed
+    Starting with this release, we will only support the HTML5 writer output,
+    and builds attempting to use the HTML4 writer will fail. If you are still
+    using the HTML4 writer, or have the ``html4_writer = True`` option in your
+    Sphinx configuration file, you will need to either remove this option or pin
+    your dependency to ``sphinx_rtd_theme<=2.0.0`` until you can.
+
+    This option was suggested in the past to work around issues with HTML5
+    support and should no longer be required to use a modern combination of this
+    theme and Sphinx.
+
+.. _release-3.0.0:
+
+3.0.0
+~~~~~
+
+This release is not yet planned, however there are plans to potentially replace
+Wyrm with Bootstrap in a release after 2.0.
+
+Also tentatively planned for this release is finally removing built CSS and
+JavaScript assets from our repository. This will remove the ability to install
+the package directly from GitHub, and instead users will be advised to install
+development releases from PyPI
