-Mamoto extension for MediaWiki
-==============================
-Version 4.0.1
- - Last update: 28 February 2019
-
-This the Mamoto (ex-Piwik) integration extension for MediaWiki
-software. The extension is only useful if you've got a MediaWiki
-installation; it can only be installed by the administrator of the site.
-
-Minimum requirements
---------------------------------
-
-1.  MediaWiki 1.25+
-
-2.  A Matomo (0.4+) installation with the site configured
-
-Installation instructions
----------------------------------
-Please, read them carefully. They're not very difficult to understand,
-but **ALL** steps are necessary:
-
-1. Create a folder called "Matomo" in your extensions directory
-
-2. Upload extension.json and Matomo.hooks.php in the "Matomo" folder you've just created
-
-3. Edit your LocalSettings.php and, at the end of the file, add the
-  following:
-
-        wfLoadExtension( 'Matomo' );
-
-
-4. Configure the Matomo URL and site-id. To do so; edit the LocalSettings and set up the following variables:
-      > $wgMatomoURL = "matomo-host.tld/dir/";
-
-      > $wgMatomoIDSite = "matomo_idsite";
-
-      **IMPORTANT** Do not define the protocol of the $wgMatomoURL
-
-  Note: Change the value of $wgMatomoURL with the URL, without the protocol
-	but including the domain name, where you installed Matomo.
-	Remember to add the trailing slash!
-
-5. Enjoy our extension!
-> Note: to check if the extension has succesfully installed; go to your wiki and check if the Matomo extension is present on the bottom of the Wiki source code.
-
-
-Custom variables
-------------------------
-* Disable cookies by setting  the ```$wgMatomoDisableCookies``` variable to ```false```.
-  > For example: $wgMatomoDisableCookies = false;
-
-* Ignore regular editors: set ```$wgMatomoIgnoreEditors``` to  ```true```
-* Ignore Bots: set ```$wgMatomoIgnoreBots``` to ```true```
-* Ignore sysop users: set ```$wgMatomoIgnoreSysops``` to ```true```
-
-* To define custom javascript tags in the Matomo javascript code, its possible to define the $wgMatomoCustomJS variable. For example if you have a single setting to insert; use the following code:
-   > ```$wgMatomoCustomJS = "_paq.push(['trackGoal', '1']);"```
-
-   If you have multiple variables to define; use an array. For example:
-   > `` $wgMatomoCustomJS = array(
-"_paq.push(['setCustomVariable', '1','environment','production']);",
-"_paq.push(['setCustomVariable', '1','is_user','yes']);"
-);``
-
-* If you want to change the title of your pages inside the Matomo tracker,
-  you can set ```$wgMatomoActionName``` inside your LocalSettings.php file.
-
-* In case you want to include the title as, for example,
-   "wiki/Title of the page", you can set ```$wgMatomoUsePageTitle``` to
-  ```true``` and set ```$wgMatomoActionName``` to ```wiki/```. The extension will print matomo_action_name = 'wiki/Title of the page';
-
-* If you want to track the username of the visitor with the Matomo feature User ID (needs Matomo >= 2.7.0) 
-  set the ```$wgMatomoTrackUsernames``` to true in LocalSettings.php.
