# Operate a Celo Node

> Run and maintain a Celo L2 node, read the protocol specification, and track the upgrades that affect operators

This section is for node operators, RPC providers, and readers of the Celo L2 protocol specification. The fastest path to a synced node is [Run a node with Docker](/operate/operators/run-node). Ask in [#celo-L2-support](https://discord.com/channels/600834479145353243/1286649605798367252) on [Discord](https://chat.celo.org) if you get stuck.

<Warning>
  Celo is replacing `op-geth` with `op-reth` as its execution client. See [End of Support for op-geth](/operate/notices/op-geth-deprecation) for each network's switch date.
</Warning>
