+## Runtime Requirements
+
+Before running a Base node, ensure your environment meets the following non-obvious requirements:
+
+- Sufficient disk space for chain data growth over time
+- Open network ports required for peer-to-peer communication
+- Stable network connectivity for syncing and RPC access
+
+Missing any of these may lead to slow syncs or unexpected runtime issues.
