-* `preset_labels`: Hash of labels that will be included with every metric when they are registered.
-* `custom_labels`: Array of names for each label that will be passed during the reporting. 
+* `preset_labels`: Hash of labels that will be included with every metric when they are registered. `Hash{Symbol (label name) => String (label value)}`
+* `custom_labels`: Hash of metrics and labels that can be applied to specific metrics. The metric name must be a registered metric. `Hash{Symbol (metric name) => Array<Symbol> (label names)}`
 * `gc_metrics_enabled`: Boolean that determines whether to record object allocation metrics per job. The default is `true`. Setting this to `false` if you don't need this metric.
 * `global_metrics_enabled`: Boolean that determines whether to report global metrics from the PeriodicMetrics reporter. When `true` this will report on a number of stats from the Sidekiq API for the cluster. This requires Sidekiq::Enterprise as the reporter uses the leader election functionality to ensure that only one worker per cluster is reporting metrics.
 * `periodic_metrics_enabled`: Boolean that determines whether to run the periodic metrics reporter. `PeriodicMetrics` runs a separate thread that reports on global metrics (if enabled) as well worker GC stats (if enabled). It reports metrics on the interval defined by `periodic_reporting_interval`. Defaults to `true`.
 * `periodic_reporting_interval`: interval in seconds for reporting periodic metrics. Default: `30`
 * `metrics_server_enabled`: Boolean that determines whether to run the rack server. Defaults to `true`

 * `registry`: An instance of `Prometheus::Client::Registry`. If you have a registry with defined metrics you can use this option to pass in your registry.
