==The basics== <!--T:1-->

===What are the differences between MediaWiki, Wikimedia, Wikipedia and wiki?=== <!--T:2-->

<!--T:3-->
This is a common question; please see <tvar|1>{{ll|Differences between Wikipedia, Wikimedia, MediaWiki, and wiki}}</> for a detailed answer.

=== I want to use a MediaWiki instance to (blank). Am I allowed to? === <!--T:4-->

<!--T:5-->
MediaWiki is free software: this means that you may use it for any purpose without legal hindrance.</translate> 
<translate>
<!--T:6-->
Furthermore, its licensing conditions apply solely to the software itself.</translate>
<translate>
<!--T:7-->
This means that although many wikis license their content under a permissive license, you are not obliged to license the content submitted to your wiki in any particular way.</translate> 
<translate>
<!--T:8-->
Of course, as a project founded to support sites like Wikipedia, we encourage you to license the texts you write under a free license, but, in short, you are not required to.

<!--T:9-->
If you wish to alter or amend the software itself, in general, you are permitted to, but there are some restrictions and you should consult [http://www.gnu.org/licenses/old-licenses/gpl-2.0.html the full text of the GNU GPL version 2 for details].</translate> 
<translate>
<!--T:10-->
Because MediaWiki is provided free of charge, there is no warranty, to the extent permitted by applicable law.

==Installation and configuration== <!--T:11-->

===Where do I download MediaWiki?=== <!--T:12-->

<!--T:13-->
[[<tvar|1>Special:MyLanguage/Download</>|Click here to download the latest stable release of MediaWiki.]] Files are supplied in a [[:en:Tar (computing)|.tar]][[:en:gzip|.gz]] archive.</translate> 
<translate>
<!--T:14-->
MediaWiki can also be [[<tvar|1>Special:MyLanguage/Download from Git</>|obtained directly from our Git]] repository.

===How to install MediaWiki?=== <!--T:15-->

<!--T:16-->
Installing MediaWiki takes around 10 to 30 minutes, and involves uploading/copying files, and running the installer script to configure the software.</translate>  
<translate>
<!--T:17-->
See <tvar|1>{{ll|Manual:Installation guide}}</>, where you will also find the ''minimum system requirements''.

===How do I install MediaWiki using a package?=== <!--T:18-->

<!--T:19-->
Many Linux distributions provide MediaWiki in a packaged format for that distribution.</translate> 
<translate>
<!--T:20-->
The MediaWiki development team refers you to your Linux distribution for assistance with installing, configuring or using them.</translate> 
<translate>
<!--T:21-->
The individual communities and companies who maintain such packages should provide installation instructions.

<!--T:22-->
Be warned that third-party distributions may be older versions, so pay close attention to compatibility information for directions and extensions.

===Can I install more than one wiki on a server using MediaWiki?=== <!--T:24-->

<!--T:25-->
It is possible to install more than one wiki on a server provided that:

<!--T:26-->
*You use a different database for each wiki</translate>
<translate><!--T:27--> Or</translate>
<translate>
<!--T:28-->
*You use a different database prefix for each wiki (for Postgres, you can achieve a similar effect by using different schemas and users)

<!--T:29-->
For information on these options, see <tvar|1>'''{{ll|Manual:$wgDBname|$wgDBname}}'''</> and <tvar|2>'''{{ll|Manual:$wgDBprefix|$wgDBprefix}}'''</> respectively.

<!--T:30-->
For information on setting up a wiki family, see <tvar|1>{{ll|Manual:Wiki family}}</>.

<!--T:31-->
For information on an alternative way of setting up more than one wiki using the same server, database and source, see [http://www.steverumberg.com/wiki/index.php/WikiHelp Steve Rumberg's] ([http://web.archive.org/web/20070715020649/http://www.steverumberg.com/wiki/index.php/WikiHelp archived version]) excellent exposé and additional comments from users.

===Does MediaWiki work with safe_mode enabled?=== <!--T:32-->

<!--T:33-->
Yes, but only to a limited degree.</translate> 
<translate>
<!--T:34-->
See [[Safe mode]] for information.

===Does MediaWiki require shell access?=== <!--T:35-->

<!--T:36-->
Shell access ([[w:Secure Shell|SSH]]) is not required for installing MediaWiki, but it is ''highly recommended''.</translate> 
<translate>
<!--T:37-->
Without shell access, it may even be difficult for you to get a backup of your wiki, or to upgrade to a new version.</translate> 
<translate>
<!--T:38-->
Some maintenance tasks are not possible at all without shell access.</translate> 
<translate>
<!--T:39-->
Many major extensions work best with shell access.

===How do I install extensions?=== <!--T:40-->

<!--T:41-->
See <tvar|1>{{ll|Manual:Extensions}}</> for information about installing and writing extensions.</translate> 
<translate>
<!--T:42-->
See <tvar|1>{{ll|Category:Extensions}}</> to find existing extensions.

===How do I add extra namespaces?=== <!--T:43-->

<!--T:44-->
See [[<tvar|1>Special:MyLanguage/Manual:Using_custom_namespaces#Creating_a_custom_namespace</>| Creating a custom namespace]].

===How do I enable uploading?=== <!--T:45-->

<!--T:46-->
File uploads are an often-used feature of MediaWiki, but are disabled by default in all current release versions.</translate> 
<translate>
<!--T:47-->
To enable them, first make the upload directory (default <tvar|1><code>images</code></>) writable by the web server (<code>[[wikipedia:chmod|chmod]] -R 777 ./images</code> or allow the Apache user to write to it, etc.) then set <tvar|2>'''{{ll|Manual:$wgEnableUploads|$wgEnableUploads}}'''</> to <tvar|3><code>true</code></> in LocalSettings.php.</translate> 
<translate>
<!--T:48-->
If you get a "failed to mkdir" error when you try to upload, it probably means that there's a permissions problem.
</translate>

<translate>
===How do I allow uploading of additional formats?=== <!--T:65-->

<!--T:66-->
MediaWiki requires that allowed file upload formats are specified using the <tvar|1>'''{{ll|Manual:$wgFileExtensions|$wgFileExtensions}}'''</> configuration directive.</translate>
