# Better Auth Integration Guide

## Documentation Version

Use documentation that matches the Better Auth version installed in the project. APIs and plugin names can differ across maintained release lines.

1. Prefer a version explicitly named by the user.
2. Otherwise, inspect the resolved `better-auth` version in the lockfile, falling back to the package manifest when no lockfile is available.
3. When the Better Auth MCP is available, call `get_doc` with `/llms.txt` to resolve that package version to a documentation identifier. Pass the identifier to every `search_docs` call and pass result paths to `get_doc` unchanged.
4. Without MCP, start at [better-auth.com/llms.txt](https://better-auth.com/llms.txt) and follow the matching version index.
5. Use the latest documentation only when the project version cannot be determined or the user explicitly asks about the latest release or an upgrade.

When planning an upgrade, separate guidance for the currently installed version from guidance for the target version.

## Setup Workflow

1. Install: `npm install better-auth`
2. Set env vars: `BETTER_AUTH_SECRET` and `BETTER_AUTH_URL`
3. Create `auth.ts` with database + config
4. Create route handler for your framework
5. Run migrations:
   - **Built-in adapter:** `npx auth@latest migrate`
   - **Drizzle:** `npx auth@latest generate --output src/db/auth-schema.ts` then `npx drizzle-kit push` (dev) or `npx drizzle-kit generate && npx drizzle-kit migrate` (prod)
