[Contract dev > Your first smart contract] Add prerequisite matrix and inline install steps (Node via nvm, testnet wallet/coins, Blueprint)

[delovoyhomie]

Problem / Why

The tutorial doesn’t clearly state prerequisites or why they’re needed, and current setup guidance sends users away mid-flow. This increases drop-off. At the same time, duplicating full install steps across many tutorials risks inconsistency.

What to do

1. Inline (keep tutorial runnable)

• Add a Prerequisites matrix near the top with “why” for:

• Wallet (approve tx)

• Testnet coins (fees)

• Node.js (run scripts/tools)

• npm (deps)

• Git (optional)

• Blueprint (scaffold/test/deploy)

• Add a short Quick Setup block with copy/paste commands:

• Install nvm, install/use Node v22+, verify versions

• Run the Blueprint scaffold command (so user can proceed immediately)

2. Canonical setup page (avoid duplication)

• Create/extend a single page: “Environment setup” (or similar) with the full details:

• nvm install variants (macOS/Linux), troubleshooting, Windows note

• Wallet + testnet faucet steps

• Blueprint overview and optional flags

• Update the tutorial to link to it as: “Need troubleshooting or Windows steps? See Environment setup.”

Acceptance criteria

• A new reader can complete setup without leaving the tutorial, using the inline quick setup block.
• Full setup instructions exist in one canonical page and are referenced from tutorials.
• Node.js uses nvm as preferred method; Blueprint scaffold command is shown inline.
• No long duplicated setup prose across multiple tutorials; only the quick block is repeated.
