# Notes for Integrators

1. For New Projects: Start with V3 using scaffold-balancer-v3 template
2. For V2 Integration: Use b-sdk or balancer-sdk with balancer-v2-monorepo as reference
3. For Smart Contracts: Reference balancer-deployments for current addresses across all networks
4. For Data Queries: Use appropriate subgraph (v2 or v3) or Dune Analytics integration
5. For Pool Math: balancer-maths provides reference implementations and test cases
6. For Routing: balancer-sor for V2, integrated router for V3

# Template Strategy

Templates (marked with template badge or in templates section) are specifically designed to be forked and customized by developers building on Balancer. They include:

• Complete working examples
• Testing infrastructure
• Deployment scripts
• Documentation
• Frontend integration (where applicable)

Core repositories are maintained by the Balancer team for protocol development and should be referenced but not directly forked for custom development.

# Monorepo Structure

Both V2 and V3 use monorepo structures:

• V2 Monorepo: Contains vault, multiple pool types, helpers, solidity utils
• V3 Monorepo: Contains vault, pools, routers, hooks, utilities

Each package within the monorepos is independently versioned and published to npm.

# Documentation Strategy

Separate documentation repositories exist for each major version:

• V1: docs-v1 (archived)
• V2: docs (maintained at docs.balancer.fi)
• V3: docs-v3 (active at docs-v3.balancer.fi)

This reflects the architectural differences between versions and allows parallel documentation maintenance.
