Can anyone tell me exactly what I'm supposed to do with line 2. of this
set of instructions:

Installation

1. Download the extension and unpack it in the extensions directory.

2. Source GlobalUsage.sql: php maintenance/sql.php
extensions/GlobalUsage/GlobalUsage.sql

Note: do this from the wiki installation where you want the GlobalUsage
data to be located. Typically this is your shared image repository.
Running update.php on that wiki will also create the table.

3. Edit LocalSettings.php and add to the bottom of the file:
require_once( "$IP/extensions/GlobalUsage/GlobalUsage.php" );

4. In LocalSettings, set $wgGlobalUsageDatabase to the identifier of the
wiki where the GlobalUsage data is located (usually the database name).
It should be something understandable to wfGetDB. Example:
$wgGlobalUsageDatabase = 'commonswiki';

At present, this can NOT be a database name of a wiki, but must be a
name given in a load balancer configuration: Manual:$wgLBFactoryConf, a
complex and largely undocumented configuration structure used by the WMF
and Wikia. For a normal mediawiki setup using multiple databases
configuring and maintaining this data structures implies significant
difficulties.

5. Run refreshGlobalimagelinks.php on all wikis in your farm. This will
take a long time. php extensions/GlobalUsage/refreshGlobalimagelinks.php

6. Visit Special:GlobalUsage and enjoy.
