 ## Motivation
 
-The main motivation for this change is that a server may take some time before fetching
-all the peers they know providing a certain CID. That will add some latency when sending
-a non-streamed response, as they need to wait for the whole discovery period.
-
-With streaming support, the server is able to respond with a *read provider record*
-as they themselves discover the peers, not needing to wait for the whole discovery
-to return the provider records.
+The main motivation for this change is to allow servers to respond faster to the
+client with provider records, as soon as they are available. In the current state,
+the client requests a list of providers for a CID from the server. Then, the client
+has to wait for the server to collect their final list of providers. After that,
+the server can respond with the full list of providers.
+
+With streaming support, the serve ris able to respond with provider records as soon
+as they are available. This reduces latency and allows for faster content discovery.
+In addition, streaming responses may produce an unlimited amount of results, which
+is not the case for non-streamed responses.
