Structure

# Project Title

Brief description (1-2 sentences)

## Overview
What problem this solves, key features

## Architecture
High-level design, data flow diagrams

## Getting Started
Prerequisites, installation, quick start

## Usage
Code examples, common patterns

## API Reference
Detailed instruction/function documentation

## Security
Security considerations, best practices

## Troubleshooting
Common issues and solutions

Code Examples

Always include:

• C# examples (for Unity integration)
• TypeScript examples (for React Native/web)
• Rust examples (for program interactions)

// Example: Wallet connection in Unity
public async Task<bool> ConnectWallet()
{
    var wallet = await Web3.Instance.LoginPhantom();
    return wallet != null;
}

// Example: Wallet connection in React Native
import { transact } from '@solana-mobile/mobile-wallet-adapter-protocol';

const connectWallet = async () => {
  const authResult = await transact(async (wallet) => {
    return await wallet.authorize({
      cluster: 'devnet',
      identity: { name: 'My Game' },
    });
  });
  return authResult;
};

Documentation for Game Developers

For Unity/Game Developers

• Focus on Solana.Unity-SDK patterns
• C#/.NET async patterns for blockchain
• PlaySolana/PSG1 integration specifics
• NFT loading and display patterns
• In-game wallet integration

For Mobile Developers

• React Native + Expo patterns
• Mobile Wallet Adapter integration

PDA Documentation

## Program Derived Addresses (PDAs)

### Player Account PDA
**Seeds:** `["player", user_pubkey]`
**Bump:** Canonical bump stored in account

```csharp
var (playerPda, bump) = PublicKey.FindProgramAddress(
    new[] { Encoding.UTF8.GetBytes("player"), user.KeyBytes },
    programId
);

const [playerPda, bump] = PublicKey.findProgramAddressSync(
  [Buffer.from("player"), user.toBuffer()],
  programId
);

## Solana-Specific Guidelines

### Compute Unit Documentation
```markdown
## Compute Units

| Instruction | Typical CU | Notes |
|-------------|-----------|-------|
| initialize  | 5,000 CU  | Includes account creation |
| update_score| 2,500 CU  | Simple state update |
| mint_reward | 8,000 CU  | Token transfer included |

Set compute budget to 1.2x typical usage.

Error Code Documentation

## Error Codes

| Code | Name | Description | Resolution |
|------|------|-------------|------------|
| 6000 | PlayerNotFound | Player account doesn't exist | Initialize player first |
| 6001 | InsufficientBalance | Not enough tokens | Add more tokens |
| 6002 | InvalidAuthority | Signer is not authority | Use correct wallet |

Quality Checklist

Before publishing documentation:

• All code examples tested and working
• Both Unity and mobile examples included where relevant
• Prerequisites listed
• Installation steps verified on clean environment
• Links to external resources work
• Diagrams render correctly
• Grammar and spelling checked
• Version/date included
• Platform-specific notes added

When to Write Docs

• Before launch: README, API docs, integration guide
• During development: Architecture decisions, complex patterns
• After changes: Update affected documentation
• Post-deployment: Deployment report, program addresses
• After audit: Security findings, mitigations

Tools and Formats

Markdown

• Primary format for all docs
• Use GitHub-flavored markdown
• Include code blocks with syntax highlighting

Diagrams

• Use Mermaid for architecture diagrams
• ASCII art for simple flows
• Screenshots for UI documentation
