+== MediaWiki Maintenance ==
+
+The .sql scripts in this directory are not intended to be run standalone,
+although this is appropriate in some cases, e.g. manual creation of blank tables
+prior to an import.
+
+Most of the PHP scripts need to be run from the command line. Prior to doing so,
+ensure that the LocalSettings.php file in the directory above points to the
+proper installation.
+
+Certain scripts will require elevated access to the database. In order to
+provide this, first create a MySQL user with "all" permissions on the wiki
+database, and then set $wgDBadminuser and $wgDBadminpassword in your
+LocalSettings.php
+
+=== Brief explanation of files ===
+
+A lot of the files in this directory are PHP scripts used to perform various
+maintenance tasks on the wiki database, e.g. rebuilding link tables, updating
+the search indices, etc. The files in the "archives" directory are used to
+upgrade the database schema when updating the software. Some schema definitions
+for alternative (as yet unsupported) database management systems are stored
+here too.
+
+The "storage" directory contains scripts and resources useful for working with
+external storage clusters, and are not likely to be particularly useful to the
+vast majority of installations. This directory does contain the compressOld
+scripts, however, which can be useful for compacting old data.
+
+=== Maintenance scripts ===
+
+As noted above, these should be run from the command line. Not all scripts are
+listed, as some are Wikimedia-specific, and some are not applicable to most
+installations.

+maintenance/dev/ scripts can help quickly setup a local MediaWiki for development purposes.
+
+Wikis setup in this way are NOT meant to be publicly available. They use a development database not acceptable for use in production. Place a sqlite database in an unsafe location a real wiki should never place it in. And use predictable default logins for the initial administrator user.
+
+Running maintenance/dev/install.sh will download and install a local copy of php 5.6, install a sqlite powered instance of MW for development, and then start up a local webserver to view the wiki.
+
+After installation you can bring the webserver back up at any time you want with maintenance/dev/start.sh

+ *
+ * Improved to resolve various bugs and better MediaWiki PHPDoc conventions:

+ * - Insert variable name after typehint instead of at end of line so that
+ *   documentation text may follow after "@var Type".
+ * - Insert typehint into source code before $variable instead of inside the comment
+ *   so that Doxygen interprets it.
+ * - Strip the text after @var from the output to avoid Doxygen warnings aboug bogus
+ *   symbols being documented but not declared or defined.

+-- SQL to create the initial tables for the MediaWiki database.
+-- This is read and executed by the install script; you should
+-- not have to run it by itself unless doing a manual install.
+
+-- This is a shared schema file used for both MySQL and SQLite installs.
+--
+-- For more documentation on the database schema, see
+-- https://www.mediawiki.org/wiki/Manual:Database_layout
+--
+-- General notes:
+--
+-- If possible, create tables as InnoDB to benefit from the
+-- superior resiliency against crashes and ability to read
+-- during writes (and write during reads!)
+--
+-- Only the 'searchindex' table requires MyISAM due to the
+-- requirement for fulltext index support, which is missing
+-- from InnoDB.
+--
+--
+-- The MySQL table backend for MediaWiki currently uses
+-- 14-character BINARY or VARBINARY fields to store timestamps.
+-- The format is YYYYMMDDHHMMSS, which is derived from the
+-- text format of MySQL's TIMESTAMP fields.
+--
+-- Historically TIMESTAMP fields were used, but abandoned
+-- in early 2002 after a lot of trouble with the fields
+-- auto-updating.
+--
+-- The Postgres backend uses TIMESTAMPTZ fields for timestamps,
+-- and we will migrate the MySQL definitions at some point as
+-- well.
+--
+--
+-- The /*_*/ comments in this and other files are
+-- replaced with the defined table prefix by the installer
+-- and updater scripts. If you are installing or running
+-- updates manually, you will need to manually insert the
+-- table prefix if any when running these scripts.
+--
+
+
+--
+-- The user table contains basic account information,
+-- authentication keys, etc.
+--
+-- Some multi-wiki sites may share a single central user table
+-- between separate wikis using the $wgSharedDB setting.
+--
+-- Note that when a external authentication plugin is used,
+-- user table entries still need to be created to store
+-- preferences and to key tracking information in the other
+-- tables.
