== Installation of Composer ==&lt;br /&gt;
Use the following commands in your terminal to install Composer : &lt;br /&gt;
&amp;lt;pre&amp;gt;&lt;br /&gt;
cd ~&lt;br /&gt;
curl -sS https://getcomposer.org/installer | sudo php&lt;br /&gt;
sudo mv composer.phar /usr/local/bin/composer&lt;br /&gt;
&amp;lt;/pre&amp;gt;&lt;br /&gt;
When moved to /usr/local/bin/composer, just type composer from any folder to run it.&lt;br /&gt;
== Upgrade ==&lt;br /&gt;
Just type the following command to update Composer&lt;br /&gt;
&amp;lt;pre&amp;gt;composer self-update&amp;lt;/pre&amp;gt;&lt;br /&gt;
== Downgrade ==&lt;br /&gt;
Composer version 2.1.14 is currently the last version not impacted by the case sensitive package name issue blocking installations and updates of Mediawiki extensions.&lt;br /&gt;
To downgrade, just use the self-update command with the version required.&lt;br /&gt;
&amp;lt;pre&amp;gt;composer self-update 2.1.14&amp;lt;/pre&amp;gt;&lt;br /&gt;
After performing any self-update, with or without version specific, you can specify --rollback to go back to the previously installed version.&lt;br /&gt;
&amp;lt;pre&amp;gt;composer self-update --rollback&amp;lt;/pre&amp;gt;&lt;br /&gt;
== pre-release version ==&lt;br /&gt;
Finally, if you are feeling adventurous, you can update to a pre-release version by executing:&lt;br /&gt;
&amp;lt;pre&amp;gt;composer self-update --preview&amp;lt;/pre&amp;gt;&lt;br /&gt;
