+## Overview
+The following service dependencies are required for running a pessimism instance:
+
+### L1 Node
+An ethereum json rpc node (e.g, go-ethereum, reth) is required for reading and syncing from recent chain state. It is best recommended to use an archival node if you're running any heuristic sessions that requires more than the last 128 blocks. Otherwise full node syncing should be sufficient assuming you're starting the application at most recent block state.
+
+### L2 Node
+An OP Stack execution node (i.e, op-reth, op-geth) is required for reading and syncing from recent chain state. It is best recommended to use an archival node if you're running any heuristic sessions that requires more than the last 128 blocks. Otherwise full node syncing should be sufficient assuming you're starting the application at most recent block state. 
+
+### OP Indexer
+The [OP Indexer](https://github.com/ethereum-optimism/optimism/tree/develop/indexer) is used as a stateful dependency for ingesting key native bridge metadata (i.e, L2 -> L1 withdrawals, supply counts).  This is only required if you'd like native bridge heuristic support (`withdrawal_enforcement`, `supply_enforcement`).
