Updated the installation documentation to include examples for using npm, pnpm, bun, and yarn. Each framework adapter (React, Vue, Angular, Solid, Lit) now includes commands for all four package managers. Additionally, added detailed examples for installing validator adapters (Zod, Yup, Valibot) with all supported package managers. This ensures comprehensive guidance for developers regardless of their preferred package management tool.
