-AnyTrust chains are an Arbitrum chain type, distinct from Arbitrum Rollup chains. The Arbitrum One mainnet chain (chain ID 42161) is — and will always be — a rollup chain. The first AnyTrust chain — Arbitrum Nova, is currently open for [developer access](https://medium.com/offchainlabs/introducing-nova-arbitrum-anytrust-mainnet-is-open-for-developers-9a54692f345e).

+AnyTrust chains are an Arbitrum chain type, distinct from Arbitrum Rollup chains. The Arbitrum One mainnet chain (chain ID 42161) is — and will always be — a rollup chain. The first AnyTrust chain — Arbitrum Nova, is currently [live on mainnet](https://medium.com/offchainlabs/its-time-for-a-new-dawn-nova-is-open-to-the-public-a081df1e4ad2); see [Public Chains](Public_Chains.md) for chain details.
 
 The fundamental tradeoff between Rollup and AnyTrust is decentralization vs. transaction costs: Rollup chains inherit their security directly from layer 1 without introducing new trust assumptions, whereas AnyTrust chains introduce their own security assumption, and are thus able to charge users lower fees.

 If you're looking to discover how Arbitrum works, the best place to begin is by the [Rollups basics](Rollup_basics.md) section, which gives a high level overview of Arbitrum's internals. From there, you can jump into more detailed explainers on various components of the system.
 
-### How Can I Start Building
+### How Can I Start Building?
 
 If you want to get started using Arbitrum with no setup required, check out our [public testnets](Public_Chains.md).
 
-### How Can I Develop Locally
+You could use our [Tutorials](https://github.com/OffchainLabs/arbitrum-tutorials) to get started with building on Arbitrum. This mono-repo includes various demos showing and explaining how to interact with Arbitrum — deploying and using contracts directly on L2, moving Ether and tokens between L1 and L2, and more.
 
-The very first step to start building with Arbitrum is [installing](Installation.md) Arbitrum and its dependencies. Next, you'll need to deploy an Arbitrum chain on an L1 blockchain. You can follow the [local testnet guide](Local_Blockchain.md) for a quickstart walkthrough deployment of an Arbitrum Rollup chain on the local testnet.
+We also show how you can use broadly supported Ethereum ecosystem tooling (Hardhat, Ethers-js, etc.) as well as our special Arbitrum SDK for convenience.
 
-Note that Arbitrum chains support dynamic launching of contracts, so you don't need to setup an Arbitrum chain for each application you build, and indeed you may deploy your contracts on a testnet chain which you did not launch. The benefits of having multiple applications on the same Arbitrum Rollup chain is that they'll be able to interact synchronously, just as they would if they were launched directly on Ethereum.
-
-Once you have deployed Arbitrum, you can [build and run the demo app](#hello-arbitrum) or [deploy your own contracts](Contract_Deployment.md).

-## Setup Local Geth and Rollup Blockchain
-
-See [Local Blockchain Setup](Local_Blockchain.md).
-
-## Hello, Arbitrum
-
-Now you'll deploy and run a demo dApp on Arbitrum. The dApp is based on
-a simple Pet Shop dApp that is used in a Truffle tutorial.
-
-First clone the pet-shop demo dApp and install dependencies:
-
-```bash
-git clone https://github.com/OffchainLabs/demo-dapp-pet-shop
-cd demo-dapp-pet-shop
-yarn
-```
-
-### Deployment
-
-Deploy contracts to Arbitrum :
-
-```bash
-truffle migrate --network arbitrum
-```
-
-### Use the dApp
-
-1. Install [Metamask](https://metamask.io/) (See all supported wallets [here](https://portal.arbitrum.one/#wallets))
-
-   > Once Metamask is installed, open it and select
-   > `Import Account` and enter one of the following pre-funded private keys
-   >
-   > ```
-   > 0x979f020f6f6f71577c09db93ba944c89945f10fade64cfc7eb26137d5816fb76

-   > 0x9af1e691e3db692cc9cad4e87b6490e099eb291e3b434a0d3f014dfd2bb747cc
-   > 0x27e926925fb5903ee038c894d9880f74d3dd6518e23ab5e5651de93327c7dffa
-   > 0xe4b33c0bb790b88f2463facaf86ae7c17cbdab41187e69ddde8cc1c1fda7c9ab
-   > ```
-
-2) Select local arbitrum network in Metamask
-
-   - Go back to Metamask or click the extension icon
-   - Select `Main Ethereum Network` top right hand side
-   - Choose `Custom RPC`
-   - Enter `Local Arbitrum` as the network name
-   - Enter `http://127.0.0.1:8547` as the RPC url
-   - Press the save button
-   - Metamask should now have an Local Arbitrum account holding ETH
-
-3) Launch the front-end
-
-   ```bash
-   yarn start
-   ```
-
-   The browser will open to [localhost:8080](http://localhost:8080)
-
-   In the popup window that appears, select `Connect`
-
-4) Adopt some pets
-
-   The pet shop dApp should now be running in your browser. Choose a pet or two
-   and click the adopt button to adopt your new animal friend(s).
-
-### Election Dapp
-
-If you want to try another dApp run, deploy the solidity contracts and launch the frontend
-
-```bash
-git clone https://github.com/OffchainLabs/demo-dapp-election
-cd demo-dapp-election
-yarn
-truffle migrate --network arbitrum
-yarn start
-```
-
-### More Demos
-
-For more demos, see our [demos](https://github.com/OffchainLabs/arbitrum-tutorials) mono-repo.
