/**
 * README template
 */
const README_TEMPLATE = `# RuVector PostgreSQL Setup

This directory contains the Docker configuration for RuVector PostgreSQL with Claude-Flow V3.

## Quick Start

\`\`\`bash
# Start the container
docker-compose up -d

# Verify it's running
docker-compose ps

# Check RuVector version
docker exec ruvector-postgres psql -U claude -d claude_flow -c "SELECT ruvector_version();"
\`\`\`

## Connection Details

| Setting | Value |
|---------|-------|
| Host | localhost |
| Port | 5432 |
| Database | claude_flow |
| Username | claude |
| Password | claude-flow-test |
| Schema | claude_flow |

## RuVector Syntax

### Extension Installation
\`\`\`sql
-- IMPORTANT: Requires explicit version
CREATE EXTENSION IF NOT EXISTS ruvector VERSION '0.1.0';
\`\`\`

### Vector Type
\`\`\`sql
-- Use ruvector(384), NOT vector(384)
CREATE TABLE embeddings (
    id UUID PRIMARY KEY,
    embedding ruvector(384)
);
\`\`\`

### Distance Operators
| Operator | Description |
|----------|-------------|
| \`<=>\` | Cosine distance |
| \`<->\` | L2 (Euclidean) distance |
| \`<#>\` | Negative inner product |

### HNSW Index
\`\`\`sql
CREATE INDEX idx_embeddings_hnsw
ON embeddings
USING hnsw (embedding ruvector_cosine_ops)
WITH (m = 16, ef_construction = 100);
\`\`\`

## Import from sql.js/JSON

\`\`\`bash
# Export current Claude-Flow memory
npx claude-flow memory list --format json > memory-export.json

# Import to RuVector PostgreSQL
npx claude-flow ruvector import --input memory-export.json
\`\`\`

## pgAdmin (Optional)

\`\`\`bash
docker-compose --profile gui up -d
\`\`\`

Access at: http://localhost:5050
- Email: admin@claude-flow.local
- Password: admin

## Troubleshooting

### Extension creation fails
Use explicit version: \`CREATE EXTENSION ruvector VERSION '0.1.0';\`

### Container won't start
\`\`\`bash
docker-compose logs postgres
docker-compose down -v
docker-compose up -d
\`\`\`
