 ## coldImport
 Syncs VulcanizeDB from Geth's underlying LevelDB datastore and persists Ethereum blocks, 
 transactions, receipts and logs into VulcanizeDB tables named `blocks`, `uncles`, 
 `full_sync_transactions`, `full_sync_receipts` and `logs` respectively.
 
-##### Usage
+#### Usage
-1. Assure node is not running, and that it has synced to the desired block height.
+1. Ensure the Ethereum node you're point at is not running, and that it has synced to the desired block height.
-1. Start vulcanize_db
+1. Run `./vulcanizedb coldImport --config <config.toml>`

 1. Optional flags:
     - `--starting-block-number <block number>`/`-s <block number>`: block number to start syncing from
     - `--ending-block-number <block number>`/`-e <block number>`: block number to sync to
     - `--all`/`-a`: sync all missing blocks
