+#!/bin/bash
+# Usage: ./build.sh [contract-name]
+# Purpose: Builds a CosmWasm smart contract using the cosmwasm/optimizer Docker image.
+# - Defaults to building the 'injective-cosmwasm-mock' contract if no argument is provided.
+# - Specify a contract name (e.g., 'atomic-order-example') to build a different contract.
+# - The contract must be a directory in 'contracts/' (e.g., 'contracts/[contract-name]').
+# - Run from the workspace root (e.g., cw-injective) to ensure access to the workspace Cargo.toml.
+# Examples:
+#   ./build.sh                    # Builds injective-cosmwasm-mock
+#   ./build.sh atomic-order-example  # Builds atomic-order-example
+#   ./build.sh dummy              # Builds dummy
+#   ./build.sh injective-cosmwasm-stargate-example  # Builds injective-cosmwasm-stargate-example
+# Output: Produces an optimized .wasm file in target/wasm32-unknown-unknown/release/
