+e.g. `curl -X POST -H 'Content-Type: application/json' --data '{"jsonrpc":"2.0","method":"statediff_writeStateDiffsInRange","params":['"$BEGIN"', '"$END"', {"intermediateStateNodes":true,"intermediateStorageNodes":true,"includeBlock":true,"includeReceipts":true,"includeTD":true,"includeCode":true}],"id":1}' "$HOST":"$PORT"`
 
-To write state diffs directly to a database:
-
-`eth-statediff-service write --config=<config path>`
-
-This depends on the `database` settings being properly configured.
+The process can be configured locally with sets of ranges to process as a "prerun" to processing directed by the server endpoints.
+This is done by turning "prerun" on in the config (`statediff.prerun = true`) and defining ranged and params in the
+`prerun` section of the config as shown below.
