+## [READY TO SIGN] Upgrade to new system config with 400m max gas limit
+
+Base is continuing to scale and we need higher block gas limit to support the increased demand.
+
+### Steps
+
+1. pull main branch of https://github.com/base-org/contract-deployments:
+`git clone [email protected]:base-org/contract-deployments.git`
+
+2. ledger needs to be connected and unlocked
+3. deploying contracts (base team):
+```
+cd mainnet/2024-11-18-increase-max-gas-limit
+make deps
+make deploy
+```
+
+4. sign (both base & op team):
+```
+cd mainnet/2024-11-18-increase-max-gas-limit
+make deps # skip if already installed
+make sign
+```
+
+5. upgrade
+```
+cd mainnet/2024-11-18-increase-max-gas-limit
+make run-upgrade
+```
