+>> standalone statediffing service ontop of LevelDB

 Purpose:

 Stand up a statediffing service directly on top of a go-ethereum LevelDB instance.
 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 the statediff RPC API:
+To serve state diffs over RPC:

-    ```bash
-    ./eth-statediff-service serve --config=<config path>
-    ```
+`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:
-    * `statediff_stateTrieAt()`
-    * `statediff_streamCodeAndCodeHash()`
-    * `statediff_stateDiffAt()`
-    * `statediff_writeStateDiffAt()`
-    * `statediff_writeStateDiffsInRange()`
+Available RPC methods are:
+  * `statediff_stateTrieAt()`
+  * `statediff_streamCodeAndCodeHash()`
+  * `statediff_stateDiffAt()`
+  * `statediff_writeStateDiffAt()`
+  * `statediff_writeStateDiffsInRange()`

-    Example:
+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"`

-    ```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"
-    ```
+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.

-* 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.
+## Configuration

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

-## Monitoring
+```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
+    url = "http://127.0.0.1:8082/"

-* 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.
-    * `ipc.count`: Unix socket connection count.
