Something's not quite right yet; make sure everything below is filled out correctly.
Site config
Wiki name:

Preferably a short word without punctuation, i.e. "Wikipedia".
Will appear as the namespace name for "meta" pages, and throughout the interface.
Contact e-mail:

Displayed to users in some error messages, used as the return address for password reminders, and used as the default sender address of e-mail notifications.
Language:

Select the language for your wiki's interface. Some localizations aren't fully complete. Unicode (UTF-8) is used for all localizations.
Copyright/license:

    * No license metadata
    * Public Domain
    * GNU Free Documentation License 1.2 (Wikipedia-compatible)
    * GNU Free Documentation License 1.3
    * A Creative Commons license - choose

A notice, icon, and machine-readable copyright metadata will be displayed for the license you pick.
Admin username:
Password:
Password confirm:

An admin can lock/delete pages, block users from editing, and do other maintenance tasks.
A new account will be added only when creating a new wiki database.

The password cannot be the same as the username.
Object caching:

    * No caching
    * Memcached

Memcached servers:

An object caching system such as memcached will provide a significant performance boost, but needs to be installed. Provide the server addresses and ports in a comma-separated list.

MediaWiki can also detect and support eAccelerator, Turck MMCache, APC, and XCache, but these should not be used if the wiki will be running on multiple application servers.

DBA (Berkeley-style DB) is generally slower than using no cache at all, and is only recommended for testing.
E-mail, e-mail notification and authentication setup
E-mail features (global):

    * Enabled
    * Disabled

Use this to disable all e-mail functions (password reminders, user-to-user e-mail, and e-mail notifications) if sending mail doesn't work on your server.
User-to-user e-mail:

    * Enabled
    * Disabled

The user-to-user e-mail feature (Special:Emailuser) lets the wiki act as a relay to allow users to exchange e-mail without publicly advertising their e-mail address.
E-mail notification about changes:

    * Disabled
    * Enabled for changes to user discussion pages only
    * Enabled for changes to user discussion pages, and to pages on watchlists (not recommended for large wikis)

For this feature to work, an e-mail address must be present for the user account, and the notification options in the user's preferences must be enabled. Also note the authentication option below. When testing the feature, keep in mind that your own changes will never trigger notifications to be sent to yourself.

There are additional options for fine tuning in /includes/DefaultSettings.php; copy these to your LocalSettings.php and edit them there to change them.
E-mail address authentication:

    * Disabled
    * Enabled

If this option is enabled, users have to confirm their e-mail address using a magic link sent to them whenever they set or change it, and only authenticated e-mail addresses can receive mails from other users and/or change notification mails. Setting this option is recommended for public wikis because of potential abuse of the e-mail features above.
Database config
Database type:

    * MySQL
    * SQLite

Database host:

If your database server isn't on your web server, enter the name or IP address here.
Database name:
DB username:Check username
DB password:and password
DB password confirm:

If you only have a single user account and database available, enter those here. If you have database root access (see below) you can specify new accounts/databases to be created. This account will not be created if it pre-exists. If this is the case, ensure that it has SELECT, INSERT, UPDATE, and DELETE permissions on the MediaWiki database.
Superuser account:  Use superuser account
Superuser name:
Superuser password:

If the database user specified above does not exist, or does not have access to create the database (if needed) or tables within it, please check the box and provide details of a superuser account, such as root, which does.
MySQL specific options
Database table prefix:

If you need to share one database between multiple wikis, or between MediaWiki and another web application, you may choose to add a prefix to all the table names to avoid conflicts.

Avoid exotic characters; something like mw_ is good.
Storage Engine
Select one:

    * InnoDB
    * MyISAM

InnoDB is best for public web installations, since it has good concurrency support. MyISAM may be faster in single-user installations. MyISAM databases tend to get corrupted more often than InnoDB databases.
Database character set
Select one:

    * MySQL 4.1/5.0 binary
    * MySQL 4.1/5.0 UTF-8
    * MySQL 4.0 backwards-compatible UTF-8

This option is ignored on upgrade, the same character set will be kept.

WARNING: If you use backwards-compatible UTF-8 on MySQL 4.1+, and subsequently back up the database with mysqldump, it may destroy all non-ASCII characters, irreversibly corrupting your backups!.

In binary mode, MediaWiki stores UTF-8 text to the database in binary fields. This is more efficient than MySQL's UTF-8 mode, and allows you to use the full range of Unicode characters. In UTF-8 mode, MySQL will know what character set your data is in, and can present and convert it appropriately, but it won't let you store characters above the Basic Multilingual Plane.
PostgreSQL specific options
Database port:
Schema for mediawiki:
Schema for tsearch2:

The username specified above (at "DB username") will have its search path set to the above schemas, so it is recommended that you create a new user. The above schemas are generally correct: only change them if you are sure you need to.
SQLite specific options
NOTE: SQLite only uses the Database name setting above, the user, password and root settings are ignored.
SQLite data directory:

SQLite stores table data into files in the filesystem. If you do not provide an explicit path, a "data" directory in the parent of your document root will be used.

This directory must exist and be writable by the web server.
MSSQL specific options
Database table prefix:

If you need to share one database between multiple wikis, or between MediaWiki and another web application, you may choose to add a prefix to all the table names to avoid conflicts.

Avoid exotic characters; something like mw_ is good.
DB2 specific options
Database port:
Schema for mediawiki:
Select one:

    * Cataloged (DB2 installed locally)
    * Uncataloged (remote DB2 through ODBC)

If you need to share one database between multiple wikis, or between MediaWiki and another web application, you may specify a different schema to avoid conflicts.
