+SIL OPEN FONT LICENSE
+
+Version 1.1 - 26 February 2007
+
+PREAMBLE
+
+The goals of the Open Font License (OFL) are to stimulate worldwide development of collaborative font projects, to support the font creation efforts of academic and linguistic communities, and to provide a free and open framework in which fonts may be shared and improved in partnership with others.
+
+The OFL allows the licensed fonts to be used, studied, modified and redistributed freely as long as they are not sold by themselves. The fonts, including any derivative works, can be bundled, embedded, redistributed and/or sold with any software provided that any reserved names are not used by derivative works. The fonts and derivatives, however, cannot be released under any other type of license. The requirement for fonts to remain under this license does not apply to any document created using the fonts or their derivatives.
+
+DEFINITIONS
+
+"Font Software" refers to the set of files released by the Copyright Holder(s) under this license and clearly marked as such. This may include source files, build scripts and documentation.
+
+"Reserved Font Name" refers to any names specified as such after the copyright statement(s).
+
+"Original Version" refers to the collection of Font Software components as distributed by the Copyright Holder(s).
+
+"Modified Version" refers to any derivative made by adding to, deleting, or substituting — in part or in whole — any of the components of the Original Version, by changing formats or by porting the Font Software to a new environment.
+
+"Author" refers to any designer, engineer, programmer, technical writer or other person who contributed to the Font Software.
+
+PERMISSION & CONDITIONS
+
+Permission is hereby granted, free of charge, to any person obtaining a copy of the Font Software, to use, study, copy, merge, embed, modify, redistribute, and sell modified and unmodified copies of the Font Software, subject to the following conditions:
+
+1) Neither the Font Software nor any of its individual components, in Original or Modified Versions, may be sold by itself.
+
+2) Original or Modified Versions of the Font Software may be bundled, redistributed and/or sold with any software, provided that each copy contains the above copyright notice and this license. These can be included either as stand-alone text files, human-readable headers or in the appropriate machine-readable metadata fields within text or binary files as long as those fields can be easily viewed by the user.
+
+3) No Modified Version of the Font Software may use the Reserved Font Name(s) unless explicit written permission is granted by the corresponding Copyright Holder. This restriction only applies to the primary font name as presented to the users.
+
+4) The name(s) of the Copyright Holder(s) or the Author(s) of the Font Software shall not be used to promote, endorse or advertise any Modified Version, except to acknowledge the contribution(s) of the Copyright Holder(s) and the Author(s) or with their explicit written permission.
+
+5) The Font Software, modified or unmodified, in part or in whole, must be distributed entirely under this license, and must not be distributed under any other license. The requirement for fonts to remain under this license does not apply to any document created using the Font Software.
+
+TERMINATION
+
+This license becomes null and void if any of the above conditions are not met.
+
+DISCLAIMER
+
+THE FONT SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO ANY WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT OF COPYRIGHT, PATENT, TRADEMARK, OR OTHER RIGHT. IN NO EVENT SHALL THE COPYRIGHT HOLDER BE LIABLE FOR ANY CLAIM, DAMAGES OR OTHER LIABILITY, INCLUDING ANY GENERAL, SPECIAL, INDIRECT, INCIDENTAL, OR CONSEQUENTIAL DAMAGES, WHETHER IN AN ACTION OF CONTRACT, TORT OR OTHERWISE, ARISING FROM, OUT OF THE USE OR INABILITY TO USE THE FONT SOFTWARE OR FROM OTHER DEALINGS IN THE FONT SOFTWARE.

-Documentation Guide
-===================
-
-Writing Documentation
----------------------
-
-Docs are generated using :doc:`Sphinx <sphinx:usage/index>`.
-
-Documentation is written in :doc:`reStructuredText
-<sphinx:usage/restructuredtext/basics>` - see this link for the basic format.
-
-In reStructuredText documents, to create the section hierarchy (mapped in HTML
-to ``<h1>`` through ``<h5>``) use these characters to underline headings in the
-order given: ``=``, ``-`` ``"``, ``'``, ``^``.
-
-Referencing other Documentation
--------------------------------
-
-Other Sphinx-built documentation, both ONF and non-ONF can be linked to using
-:doc:`Intersphinx <sphinx:usage/extensions/intersphinx>`.
-
-You can see all link targets available on a remote Sphinx's docs by running::
-
-  python -msphinx.ext.intersphinx http://otherdocs/objects.inv
-
-Building the Docs
-------------------
-
-The documentation build process is stored in the ``Makefile``. Building docs
-requires Python to be installed, and most steps will create a virtualenv
-(``venv_docs``) which contains the required tools.  You may also need to
-install the ``enchant`` C library using your system's package manager for the
-spelling checker to function properly.
-
-Run ``make html`` to generate html documentation in ``_build/html``.
-
-To check the formatting of documentation, run ``make lint``. This will be done
-in Jenkins to validate the documentation, so please do this before you create a
-patchset.
-
-To check spelling, run ``make spelling``. If there are additional words that
-are correctly spelled but not in the dictionary (acronyms, trademarks, etc.)
-please add them to the ``dict.txt`` file.
-
-Creating new Versions of Docs
------------------------------
-
-To change the version shown on the built site, change the contents of the
-``VERSION`` file.
-
-There is a ``make multiversion`` target which will build all versions published
-on the remote to ``_build``. This will use `sphinx-multiversion
-<https://github.com/Holzhaus/sphinx-multiversion>`_ to build multiple versions
-of the site.
-
-Adding Images and Diagrams
---------------------------
-
-There are multiple ways to add images and diagrams to the documentation.
-Generally, you should prefer using `SVG
-<https://en.wikipedia.org/wiki/Scalable_Vector_Graphics>`_ images, as these can
-be scaled to any size without quality loss.
-
-If you're creating diagrams, there are multiple tools available.
-:doc:`Graphviz <sphinx:usage/extensions/graphviz>` can render inline text-based
-graphs definitions and diagrams within the documentation, and is best for
-simple diagrams.
-
-More complex diagrams can be created in `Diagrams.net/Draw.io
-<https://www.diagrams.net/>`_ format. When saving these diagrams, use the
-SVG format, and check the "Include a copy of my diagram". This will let
-someone open the SVG later directly from the documentation and edit it, without
-any loss in functionality or quality.
-
-The last resort is to use raster images. If they're drawings or screen
-captures, use the `PNG
-<https://en.wikipedia.org/wiki/Portable_Network_Graphics>`_ format.  Consider
-compressing them with a tool like `OptiPNG <http://optipng.sourceforge.net/>`_,
-or `pngquant <https://pngquant.org/>`_.  If it's a photograph, use `JPEG
-<https://en.wikipedia.org/wiki/JPEG>`_.
