 This tutorial serves as a comprehensive guide for deploying your rollup on Celestia's data availability (DA) network. From the Rollkit perspective, there's no difference in posting blocks to Celestia's testnets or Mainnet Beta.

 ## 🪶 Running a Celestia light node
 
 Before you can start your rollup node, you need to initiate, sync, and fund a light node on one of Celestia's networks on a compatible version:

 ## 🏗️ Prerequisites {#prerequisites}
 
-- `rollkit` CLI installed from the [quick start](/tutorials/quick-start) tutorial.
+- `gmd` CLI installed from the [gm-world](/tutorials/gm-world) tutorial.
 
 ## 🛠️ Configuring flags for DA
 
 Now that we are posting to the Celestia DA instead of the local DA, the `rollkit start` command requires three DA configuration flags:
 
-- `--rollkit.da_start_height`
-- `--rollkit.da_auth_token`
-- `--rollkit.da_namespace`
+- `--rollkit.da.start_height`
+- `--rollkit.da.auth_token`
+- `--rollkit.da.namespace`

-Optionally, you could also set the `--rollkit.da_block_time` flag. This should be set to the finality time of the DA layer, not its actual block time, as Rollkit does not handle reorganization logic. The default value is 15 seconds.
