 # How to use IBC token (TIA) as gas token in your rollup
 
 ## 🌞 Introduction {#introduction}
 
 This tutorial will guide you through building a sovereign `gm-world` rollup using Rollkit, with TIA as the gas token. Unlike the [quick start guide](/guides/quick-start.md), which uses a native rollup token for gas, this tutorial demonstrates how to integrate an IBC-enabled token, TIA, as the gas token within the rollup, providing a deeper exploration of sovereign rollup development.
 
-We will cover:
+No prior understanding of the build process is required, just that it utilizes the [Cosmos SDK](https://github.com/cosmos/cosmos-sdk) for blockchain applications.
 
-- Building and configuring a Cosmos-SDK application-specific rollup blockchain.
-- Posting rollup data to a Data Availability (DA) network.
-- Executing transactions using TIA as the gas token (the end goal).

+Before proceeding, ensure that you have completed the [build a chain](/guides/gm-world.md) tutorial, which covers setting-up, building and running your chain.

-## 🛠️ Dependencies {#dependencies}
-
-Rollkit uses the [Go programming language](https://go.dev/dl/). Here's how to install it:
-
-- **Linux or macOS**: Run the provided script:
-
-  ```bash-vue
-  curl -sSL https://rollkit.dev/install-go.sh | bash -s {{constants.golangVersion}}
-  ```
-

-
-## 📦 Install Rollkit (CLI) {#install-rollkit}
-
-To install Rollkit, run the following command in your terminal:
-
-```bash-vue
-curl -sSL https://rollkit.dev/install.sh | sh -s {{constants.rollkitLatestTag}}
-```
-
-Verify the installation by checking the Rollkit version:
-
-```bash
-rollkit version
-```
-
-A successful installation will display the version number and its associated git commit hash.

-## 🌐 Running a Local DA Network {#running-local-da}
+## Setup your local DA network {#setup-local-da}
 
-Learn to run a local DA network, designed for educational purposes, on your machine.

-To set up a local DA network node:
-
-```bash-vue
-(cd /tmp && curl -sSL https://rollkit.dev/install-local-da.sh | bash -s {{constants.localDALatestTag}})
-```
-
-This script builds and runs the node, now listening on port `7980`.

-## 🏗️ Building Your Sovereign Rollup {#building-your-sovereign-rollup}
-
-With the local DA network running, let’s prepare your rollup blockchain.
-
-To make it simple, we will download a repository with a `gm-world` rollup that includes an `init.sh` script to handle all the setup for you.

-Download and build a `gm-world` rollup with an interactive script in a new terminal:

-Ensure the `jq` command line tool is installed before proceeding. Install it using `sudo apt-get install jq` on Ubuntu or `brew install jq` on macOS.

-::: tip
-If you get errors of `gmd` not found, you may need to add the `go/bin` directory to your PATH. You can do this by running `export PATH=$PATH:$HOME/go/bin` and then running the `init.sh` script manually again.

-## 🛠️ Initialize Rollkit TOML Configuration {#initialize-rollkit-configuration}
-
-Change to the `gm` directory and initialize the rollkit toml configuration:
+Your local DA network is already running if you followed the [quick start guide](/guides/quick-start.md) or the [build a chain](/guides/gm-world.md). If not, you can start it with the following command:
 
 ```bash
-cd ./gm && rollkit toml init
-```
-
-Edit the `rollkit.toml` file to include the following configuration:
-
-```toml
-entrypoint = "/root/gm/cmd/gmd/main.go"
-
-[chain]
-  config_dir = "./.gm"

 ```
 
 ## 🚀 Starting your rollup {#start-your-rollup}
 
 Start the rollup, posting to the local DA network:

 ```
 
 Note that we specified the gas token to be IBC TIA. We still haven't made an IBC connection to Celestia's Mocha testnet, however, if we assume our first channel will be an ICS-20 transfer channel to Celestia, we can already calculate the token denom using this formula:
