    ```
    Import-Module "$PSScriptRoot\..\PSCI\PSCI.psd1" -Force
 
    # clear any old Environment definitions - required only for -NoConfigFiles deployments
    $Global:Environments = @{}
 
    Environment Local {
        ServerConnection WebServer -Nodes localhost
        ServerRole Web -Steps 'PSCIEventLogSource' -ServerConnection WebServer
 
        Tokens Web @{
            EventLogSources = @(
                @{ Name = 'MyEventLogSource' },
                @{ Name = 'MyEventLogSource2'; LogName = 'MyLogName' }
            )
        }
