 In this tutorial, you'll **compose with someone else's contracts** on Flow testnet. You'll write a Cadence transaction that reads public state from a contract named `Counter` and only increments the counter when it is odd. Then you'll extend the transaction to mint NFTs when the counter is odd, demonstrating how to compose multiple contracts in a single transaction. Everything runs against testnet using the Flow CLI and the dependency manager.

 # Native Data Availability With Cadence Scripts
 
-## Overview
-
 In Solidity, you can only retrieve data from **view** functions that the contract author anticipated and included in the original contract. If the exact query you want is not exposed, teams typically rely on a _data availability service_ such as The Graph, Covalent, Alchemy Enhanced APIs, Reservoir, or NFTScan to compute and serve that view.
 
 In Cadence, **scripts** are general-purpose read programs. They can traverse public account storage, read public capabilities, and compose types from multiple contracts to answer new questions without modifying those contracts. You are not limited to the pre-written surface area of a single contract's views.

 - **Cadence scripts are flexible**: You compose types across modules, traverse account storage, and read public capabilities at query time. You do not need to redeploy contracts to answer new questions.

 # Upgrading Cadence Contracts
 
-## Overview

 In Cadence, you can upgrade deployed contracts by adding new functionality while preserving existing state and maintaining the same contract address. Unlike other blockchain platforms that require complex proxy patterns or complete redeployment, Cadence allows you to seamlessly extend your contracts with new functions and events through multiple incremental upgrades.
