+## dictionaryRequestCacheStrategyPromise
+installYamcsPlugin also accepts an optional promise argument `dictionaryRequestCacheStrategyPromise`. This strategy is passed to the request for loading the YAMCS dictionary, or the `#loadTelemetryDictionary` function in `object-provider.js`. An example of how to make use of this is below.
