-Your contract will need a reference to the [`IBundleAggregatorProxy`](/data-feeds/mvr-feeds/api-reference#ibundleaggregatorproxy) interface so it can:
+Your contract will need to interact with the MVR feed's proxy contract. The [`IBundleAggregatorProxy`](/data-feeds/mvr-feeds/api-reference#ibundleaggregatorproxy) interface provides the necessary functions:
 
-- Retrieve the raw bytes via [`latestBundle()`](/data-feeds/mvr-feeds/api-reference#latestbundle).
-- Retrieve decimals via [`bundleDecimals()`](/data-feeds/mvr-feeds/api-reference#bundledecimals) if the feed includes numeric fields.
-- Check the timestamp of the last update via [`latestBundleTimestamp()`](/data-feeds/mvr-feeds/api-reference#latestbundletimestamp).
+- [`latestBundle()`](/data-feeds/mvr-feeds/api-reference#latestbundle): Retrieves the raw data bundle.
+- [`bundleDecimals()`](/data-feeds/mvr-feeds/api-reference#bundledecimals): Retrieves the decimal places for numeric fields.
+- [`latestBundleTimestamp()`](/data-feeds/mvr-feeds/api-reference#latestbundletimestamp): Retrieves the timestamp of the last update.
