-To get started quickly, let's walk you through our standard demo setup consisting of 
+* A cluster of three `hydra-nodes`, each directly connected to the others and configured with one of three Hydra credentials: `Alice`, `Bob`, or `Carol`
+* A single `cardano-node` producing blocks used as a (very fast) local `devnet`
+* The `hydra-tui` example for clients to interact with the individual `hydra-node`.
 
-- a cluster of three `hydra-node`, directly connected to each other, each having access to one of three Hydra credentials `alice`, `bob`, or `carol`;
-- a single `cardano-node` producing blocks used as a (very fast) local `devnet`;
-- the `hydra-tui` example clients to interact with the individual Hydra nodes.
+This tutorial uses [Docker](https://www.docker.com/get-started) to install the nodes, so ensure Docker is installed. If you want to explore alternative ways of running the tools, see the [variant tutorial](./getting-started-without-docker.md) or the [testnet tutorial](./tutorial/index.md), which uses pre-built binaries. The documentation pages on [installation](./installation) and [configuration](./configuration) provide more details.

 ## Use the head
 
-Using the terminal interface of any node, you can now `[i]nit` the Hydra head and `[c]ommit` pre-distributed funds to it. Note that these steps are near instant as the devnet is producing blocks much faster than a public testnet or the mainnet. After committing from all nodes, the head will automatically open and you can also use the `hydra-tui` or the API to create new transactions and submit them to the Hydra head.
