+As described in [Nodes](/architecutre/nodes), Tezos nodes are peer-to-peer programs that run the Tezos network.
+Anyone can run a node, and they might do so for many different reasons, including:
+
+- Running nodes makes the Tezos network resilient and secure
+- Public nodes may have rate limits, so running your own node allows you to send unlimited requests to it to get information about Tezos or to send transactions from your dApps
+- Running a node is part of being a baker and receiving the rewards for baking
+
+This tutorial covers setting up a Tezos node as a baker, which includes running these processes:
+
+- An Octez node, sometimes referred to as a Tezos node
+- A baker daemon
+- A [Data Availability Layer](/architecture/data-availability-layer) node
+
+## Why is a DAL node needed?
+
 The Tezos data availability layer (DAL) is a peer-to-peer network that Tezos Smart Rollups can use to fetch data securely.
 The DAL is a key component for the scalability and bandwidth of Tezos and it's important for bakers to run DAL nodes along with their layer 1 nodes.
 
-## Why are DAL bakers needed?
-
 When users and dApps submit data to the DAL, bakers use DAL nodes to verify that the data is available.
 Then the bakers attest that the data is available.
 Smart Rollup nodes can retrieve the data from DAL nodes only when enough bakers have attested that the data is available.

-Now that you have a DAL node, you can run a baking daemon that can attest to DAL data or restart an existing baking daemon to connect it to the DAL node.
+Now that you have a layer 1 node and a DAL node, you can run a baking daemon that can create blocks and attests to DAL data.
+If you already have a baking daemon, you can restart it to connect to the DAL node.
 
 1. To run a baking daemon that connects to the DAL, start it as usual and pass the URL to your DAL node to it with the `--dal-node` argument:

 The DAL node is responsible for temporarily storing data and providing it to bakers and Smart Rollups.
+Follow these steps to run the DAL node:
 
 1. Ensure that the port that the DAL node runs on (by default, 11732) is accessible from outside its system.
 You may need to adapt your firewall rules or set up network address translation (NAT) to direct external traffic to the DAL node.
