-CONTRIBUTING TO MOODLE
-======================
-
-Moodle is made by people like you. We are members of a big worldwide community
-of developers, designers, teachers, testers, translators and other users. We
-work in universities, schools, companies and other places. You are very welcome
-to join us and contribute to the project.
-
-See <https://docs.moodle.org/dev/Contributing_to_Moodle> for the many ways you
-can help, not only with coding.
-
-Moodle is open to community contributions to core, though all code must go
-through peer-review, automated behaviour testing, continuous integration and
-human post-integration checks.
-
-Pull requests
-------------
-
-Please do not open pull requests via Github. The repository there is just a
-mirror of the official repository at <https://git.moodle.org>. Issues are
-reported and patches provided via <https://tracker.moodle.org>. See below for
-more information.
-
-Moodle core bug fixes and new features
--------------------------------------
-
-During the years of intensive development, a mature process of including
-submitted patches has evolved.
-
-* Every bug fix or new feature must have a tracker issue.
-* You publish the branch implementing the fix or new feature in your public
-  clone of the moodle.git repository (typically on Github).
-* Your patch is peer-reviewed, discussed, integrated, tested and then released
-  as a part of moodle.git.
-* New features are developed on the master branch. Bug fixes are also
-  backported to currently supported maintenance (stable) branches.
-
-For further details, see <https://docs.moodle.org/dev/Process>.
-
-Moodle plugins
--------------
-
-Moodle has a framework for additional plugins to extend its functionality. We
-have a Moodle plugins directory <https://moodle.org/plugins/> where you can
-register and maintain your plugin. Plugins hosted in the plugins directory can
-be easily installed and updated via the Moodle administration interface.
-
-* You are expected to have a public source code repository with your plugin
-  code.
-* After registering your plugin in the plugins directory it is reviewed before
-  being published.
-* You are expected to continuously release updated versions of the plugin via
-  the plugins directory. We do not pull from your code repository; you must do
-  it explicitly.
-
-For further details, see <https://docs.moodle.org/dev/Plugin_contribution>.

-Here is a short summary of the installation process (which can take just a few
-minutes):
-
-1. Move the Moodle files into your web directory.
-
-2. Create a single database for Moodle to store all its tables in (or choose an
-   existing database).
-
-3. Visit your Moodle site with a browser. You should be taken to the
-   install.php script, which will lead you through creating a config.php file
-   and then setting up Moodle, creating an admin account etc.
-
-4. Set up a cron task to call the file admin/cron.php every minute.
-
-For more information, see <https://docs.moodle.org/en/Installing_Moodle>.

+QUICK INSTALL
+=============

-Moodle - the world's open source learning platform
+For the impatient, here is a basic outline of the
+installation process, which normally takes me only
+a few minutes:

-Moodle <https://moodle.org> is a learning platform designed to provide
-educators, administrators and learners with a single robust, secure and
-integrated system to create personalised learning environments.
+1) Move the Moodle files into your web directory.

-You can download Moodle <https://download.moodle.org> and run it on your own
-web server, ask one of our Moodle Partners <https://moodle.com/partners/> to
-assist you, or have a MoodleCloud site <https://moodle.com/cloud/> set up for
-you.
+2) Create a single database for Moodle to store all
+   its tables in (or choose an existing database).

-Moodle is widely used around the world by universities, schools, companies and
-all manner of organisations and individuals.
+3) Visit your Moodle site with a browser, you should
+   be taken to the install.php script, which will lead
+   you through creating a config.php file and then
+   setting up Moodle, creating an admin account etc.

-Moodle is provided freely as open source software, under the GNU General Public
-License <https://docs.moodle.org/dev/License>.
+4) Set up a cron task to call the file admin/cron.php
+   every five minutes or so.

-Moodle is written in PHP and JavaScript and uses an SQL database for storing
-the data.

-See <https://docs.moodle.org> for details of Moodle's many features.
+For more information, see the INSTALL DOCUMENTATION:
+
+   http://docs.moodle.org/en/Installing_Moodle

-MOODLE TRADEMARKS POLICY
-========================
+------------------------
+Moodle Trademark License
+------------------------

-The word "Moodle" is trademarked in many countries around the world. The word
-was originally an acronym: Modular Object-Oriented Dynamic Learning
-Environment. The trademark is owned by Martin Dougiamas, Founder and Director
-of Moodle.
+The name Moodle™ is a registered trademark of the Moodle Trust.

-The law obligates trademark owners to police their marks and prevent the use of
-confusingly similar names by third parties. Through this policy we’d like to
-make it clear how Moodle-related projects, organisations, and people can use
-the Moodle trademark. We’d also like to be clear about how use of the word is
-restricted when used to promote commercial Moodle services. We do this to
-protect the very business model that allows us to continue developing Moodle
-for you.
+A key part of the business model that allows us to produce and
+distribute Moodle as completely Free open source software is that
+we restrict the commercial use of the Moodle trademark to those
+who have contracted to support Moodle development (Moodle Partners).

-Allowed uses
------------
+If you are intending to use the name (and/or logo) to advertise
+generic Moodle™ services (eg Moodle Hosting, Moodle Support,
+Moodle Certification, Moodle Training, Moodle Consulting,
+Moodle Customisation, Moodle Courseware Development, Moodle
+Theme design, Moodle Integrations, Moodle Installations, etc)
+or as the name of a software package, then you must seek
+direct permission in writing from the Moodle Trust via the
+moodle.com helpdesk, in accordance with normal trademark
+restrictions.

-The following uses don’t require any permission at all:
+There are no restrictions on how you use the name in other
+contexts (for example, if you use Moodle just to provide
+courses then you can use the name freely to refer to it.)

-* Referring to the software or the Moodle project.
-* Describing your own Moodle implementation (including within corporate

-    --component=<frankenstyle>  Name of the component the variable is part of. Defaults to core.
-    --name=<configname>         Name of the configuration variable to get/set. If missing, print all
-                                configuration variables of the given component.
-    --set=<value>               Set the given variable to this value.
-    --unset                     Unset the given variable.
-    --shell-arg                 Escape output values so that they can be directly used as shell script arguments.
-    --json                      Encode output list of values using JSON notation.
-    --no-eol                    Do not include the trailing new line character when printing the value.
-
-The list of all variables of the given component can be printed as
-tab-separated list (default) or JSON object (--json). Particular values are
-printed as raw text values, optionally escaped so that they can be directly
-used as shell script arguments (--shell-arg). Single values are displayed with
-trailing new line by default, unless explicitly disabled (--no-eol).
-
-In the read mode, the script exits with success status 0 if the requested value
-is found. If the requested variable is not set, the script exits with status 3.
-When listing all variables of the component, the exit status is always 0 even
-if no variables for the given component are found. When setting/unsetting a
-value, the exit status is 0. When attempting to set/unset a value that has
-already been hard-set in config.php, the script exits with error status 4. In
-case of unexpected error, the script exits with error status 1.
-
-Examples:
-
-    # php cfg.php
-        Prints tab-separated list of all core configuration variables and their values.
-
-    # php cfg.php --json
-        Prints list of all core configuration variables and their values as a JSON object.
-
-    # php cfg.php --name=release
-        Prints the given configuration variable - e.g. \$CFG->release in this case.
-
-    # php cfg.php --component=tool_recyclebin
-    #   Prints tab-separated list of the plugin's configuration variables.
-
-    # export DATAROOT=\$(php cfg.php --name=dataroot --shell-arg --no-eol)
-        Stores the given configuration variable in the shell variable, escaped
-        so that it can be safely used as a shell argument.
-
-    # php cfg.php --name=theme --set=clean
-        Sets the given configuration variable to the given value.
-
-    # php cfg.php --name=noemailever --unset
-        Unsets the previously configured variable.
