+# GM world rollup: Deploying to Avail  
+
+## 🌞 Introduction {#introduction}
+
+Avail DA offers scalable data availability that underpins the Avail ecosystem and ensures instantaneous and reliable data integrity, enabling rollups to grow, through the use of cutting-edge zero knowledge and KZG Polynomial commitments.
+
+This tutorial serves as a comprehensive guide for deploying your GM world rollup on Avail's data availability (DA) network.
+
+Before proceeding, ensure that you have completed the [GM world rollup](/tutorials/gm-world) tutorial, which covers setting up a local sovereign gm-world rollup and connecting it to a local (mock) DA node.
+
+## 🪶 Running an avail light node
+
+Before you can start your rollup node, you need to initiate, sync, and possibly fund a light node on Turing testnet which is the test network of Avail
+
+- [Local Development](https://github.com/rollkit/avail-da/blob/main/README.md)
+- [Turing Testnet](https://docs.availproject.org/docs/networks)
+
+### 🚀 Using Turing Testnet
+
+- To fund your wallet address for using Turing Testnet: get AVAIL tokens from [Faucet]((https://faucet.avail.tools/))
+- Paste your mnemonic in the `identity.toml` file by creating a `identity.toml` with the following command:
+```touch identity.toml```
+Example:
+```bash
+avail_secret_uri = '<paste your mnemonic here>'
+```
+- Running just an Avail light node is enough for Turing testnet. Run the Avail light node using the following command
+```bash
+cargo run --release -- --network turing --app-id 1 --clean --identity identity.toml
+```
+
+If you want to sync avail light node with your desired block number, you can add the following config in your `config.yaml` file from [here](https://github.com/availproject/avail-light/blob/main/config.yaml.template)
+```bash
+http_server_host = '127.0.0.1'
+http_server_port = 8000
+port = 38000
+sync_start_block = 322264
+```
+
+After successfully starting a light node, it's time to start posting the batches of blocks of data that your rollup generates.
+
+## 🧹 Cleaning previous chain history
+
+From the [GM world rollup](/tutorials/gm-world) tutorial, you should already have the `gmd` binary and the `$HOME/.gm` directory.
+
+To clear old rollup data:
+
+```bash
+rm -r $(which gmd) && rm -rf $HOME/.gm
+```
+
+## 🏗️ Building your rollup
+
+Now we need to rebuild our rollup by simply running the existing `init.sh` script:
+
+```bash
+cd $HOME/gm && bash init.sh
+```
+
+This process creates a new `$HOME/.gm` directory and a new `gmd` binary. Next, we need to connect our rollup to the running avail light node.
+
+## 🛠️ Configuring flags for DA
+
+Now we're prepared to initiate our rollup and establish a connection with the avail light node. The `gmd start` command requires two DA configuration flags:
+
+- `--rollkit.da_start_height`
+- `--rollkit.da_address`
+
+Let's determine what to provide for each of them.
+
+First, let's query the DA Layer start height using an RPC endpoint provided by avail Labs. For local it would be - [https://localhost:8000/v1/latest_block](https://localhost:8000/v1/latest_block), and for turing testnet - [https://rpc.lunaroasis.net/block](https://rpc.lunaroasis.net/block)
+
+Here is an example for the local development (replace URL for Turing Testnet if needed):
+
+```bash
+DA_BLOCK_HEIGHT=$(curl https://localhost:8000/v1/latest_block | jq -r '.result.block.header.height')
+echo -e "\n Your DA_BLOCK_HEIGHT is $DA_BLOCK_HEIGHT \n"
+```
+
+You will see the output like this:
+
+```bash
+ Your DA_BLOCK_HEIGHT is 35
+```
+
+## 🔥 Running your rollup connected to an avail light node
+
+Now let's run our rollup node with all DA flags:
+
+```bash
+    gmd start \
+    --rollkit.aggregator \
+    --rollkit.da_address="grpc://localhost:3000" \   
+    --rollkit.da_start_height $DA_BLOCK_HEIGHT \
+    --minimum-gas-prices="0.1stake"
+```
+
+Now, the rollup is running and posting blocks (aggregated in batches) to avail. You can view your rollup by finding your account on [Turing testnet](https://avail-turing.subscan.io/)
+
+::: info
+For details on configuring gas prices specifically for the DA network, see our [DA Network Gas Price Guide](/guides/gas-price). This is separate from the `--minimum-gas-prices="0.025stake"` setting, which is used for rollup network operations.
+:::
+
+## 🎉 Next steps
+
+Congratulations! You've built a local rollup that posts to avail's testnets as well as locally. Well done! Now, go forth and build something great! Good luck!
