Documentation Standards

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:

• **Anchor examples** (most common)
• **Frontend TypeScript examples** (@solana/kit)
• **Rust client examples** (for backend integrations)

// Example: Calling initialize instruction
const tx = await program.methods
  .initialize()
  .accounts({
    vault: vaultPda,
    authority: wallet.publicKey,
    systemProgram: SystemProgram.programId,
  })
  .rpc();

IDL Documentation Pattern

Document every instruction with:

### `initialize`

Initializes a new vault account.

**Accounts:**
- `vault` (mut, init): The vault PDA to create
- `authority` (signer): The authority that will control the vault
- `systemProgram`: Solana System Program

**Arguments:**
- None

**Access Control:**
- Requires `authority` to be a signer
- Vault must not already exist

**Errors:**
- `VaultAlreadyExists`: If vault PDA already initialized

**Example:**
\`\`\`typescript
const [vaultPda] = PublicKey.findProgramAddressSync(
  [Buffer.from("vault"), authority.toBuffer()],
  programId
);
\`\`\`

Best Practices

Clarity

• Write for developers who may not know Solana
• Explain Solana-specific concepts (PDAs, CPIs, rent)
• Use clear, active voice
• Include "Why" along with "How"

Completeness

• Document ALL public instructions
• Include error codes with explanations
• Provide complete examples that work
• Link to relevant Solana documentation

Maintainability

• Keep docs close to code (in repo)
• Version documentation with code
• Update docs when code changes
• Include "Last Updated" dates

Security Documentation

Always include:

• Attack vector analysis
• Access control patterns
• Important security considerations
• Audit status and findings
