+This guide offers a bare-bones introduction to getting up and running with Nimbus and [Rocket Pool](https://www.rocketpool.net/) -- a trustless staking pool which matches those who wish to stake some ETH with those who wish to operate a node.
+
+> **Nota Bene:** Rocket Pool is not only for node operators. Staking in Rocket Pool as a regular user is as easy as navigating to the [Rocket Pool website](https://beta.rocketpool.net/), entering an amount of ETH to stake, and clicking Start! When you stake, you will immediately receive an amount of rETH with equivalent value to the ETH you deposit. This allows anyone, no matter how technical or wealthy, to help contribute to the decentralisation of the network.
