 This service can serve historical state data over the same rpc interface as

 ## Usage

+* Create / update the config file (refer to example config above).
+
 ### `serve`

-To serve state diffs over RPC:
+* To serve the statediff RPC API:

-`eth-statediff-service serve --config=<config path>`
+    ```bash
+    ./eth-statediff-service serve --config=<config path>
+    ```

-Example:
+    Example:

-```bash
-./eth-statediff-service serve --config environments/config.toml
-```
+    ```bash
+    ./eth-statediff-service serve --config environments/config.toml
+    ```

-Available RPC methods are:
-  * `statediff_stateTrieAt()`
-  * `statediff_streamCodeAndCodeHash()`
-  * `statediff_stateDiffAt()`
-  * `statediff_writeStateDiffAt()`
-  * `statediff_writeStateDiffsInRange()`
+* Available RPC methods:
+    * `statediff_stateTrieAt()`
+    * `statediff_streamCodeAndCodeHash()`
+    * `statediff_stateDiffAt()`
+    * `statediff_writeStateDiffAt()`
+    * `statediff_writeStateDiffsInRange()`

-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"`
+    Example:

-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.
+    ```bash
+    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"
+    ```

-## Configuration
+* Prerun:
+    * 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 ranges and params in the
+`prerun` section of the config.
+    * Set the range using `prerun.start` and `prerun.stop`. Use `prerun.ranges` if prerun on more than one range is required.

-An example config file:
+* NOTE: Currently, `params.includeTD` must be set to / passed as `true`.

-```toml
-[leveldb]
-    mode = "local"
-    # path and ancient LevelDB paths required in local mode
-    path = "/Users/user/Library/Ethereum/geth/chaindata"
-    ancient = "/Users/user/Library/Ethereum/geth/chaindata/ancient"
-    # url for leveldb-ethdb-rpc endpoint required in remote mode

-    ipcPath = ".ipc"
-    httpPath = "127.0.0.1:8545"
+* Enable metrics using config parameters `prom.metrics` and `prom.http`.
+* `eth-statediff-service` exposes following prometheus metrics at `/metrics` endpoint:
+    * `ranges_queued`: Number of range requests currently queued.
+    * `loaded_height`: The last block that was loaded for processing.
+    * `processed_height`: The last block that was processed.
+    * `stats.t_block_load`: Block loading time.
+    * `stats.t_block_processing`: Block (header, uncles, txs, rcts, tx trie, rct trie) processing time.
+    * `stats.t_state_processing`: State (state trie, storage tries, and code) processing time.
+    * `stats.t_postgres_tx_commit`: Postgres tx commit time.
+    * `http.count`: HTTP request count.
+    * `http.duration`: HTTP request duration.
