Fixes #8203.

Every Prisma 8 getting-started page starts from a generated template (npm create prisma or orm init). The issue asks for a plain tutorial that builds a project by hand: npm init, install the packages, one config file, one contract, one index.ts that writes and reads, then a schema change and a migration.

  • New page /prisma-orm/from-scratch (PostgreSQL only): create the project, write prisma.config.ts and .env, write prisma/contract.prisma, run contract emit and db init, run a single index.ts with tsx, add a field, run migration plan and db migrate --advance-ref db, then migration status to verify. It names the Prisma 8 equivalents of generate and migrate dev once, since that is the vocabulary the reporters used.
  • Registered in (index)/prisma-orm/meta.json between quickstart and add-to-existing-project.
  • One sentence linking to it from the PostgreSQL quickstart and from the Prisma ORM landing page.
Validation
  • Every command and file on the page was executed in a fresh directory against a fresh npx create-db@latest database, twice (once while writing, once as an independent re-run from the page text). Installed: prisma@8.0.0-rc.15, @prisma/orm-postgres@8.0.0-rc.11, tsx@4.23.13, typescript@5.9.3, dotenv@18.0.0. The index.ts output and the contract hashes in the expected-output blocks are the real ones from those runs.
  • The expected-output blocks are trimmed: they leave out dotenv's injected env line, the contract emit hash lines, and the CLI's → next step hints. Note for a separate fix: those hints print a literal {bin} placeholder (→ Apply the migration: {bin} db migrate).
  • check-ai-signs.sh clean on the three touched pages; cspell clean; pnpm lint:links 0 errors.

Summary by CodeRabbit

  • Documentation
    • Added a comprehensive guide for setting up Prisma ORM 8 with PostgreSQL from scratch.
    • Documented installation, configuration, schema creation, database initialization, CRUD operations, migrations, verification, and troubleshooting.
    • Added the new setup guide to Prisma ORM documentation navigation.
    • Updated the Prisma ORM introduction and PostgreSQL quickstart with links to the manual setup guide.

Every Prisma 8 getting-started page runs `npm create prisma` or `orm
init` and starts from a generated template, and #8203 asked for a plain
tutorial that builds a project by hand: init, install, one config file,
one contract, one `index.ts` that reads and writes, then a schema change
and a migration.

This adds `(index)/prisma-orm/from-scratch.mdx` (PostgreSQL only),
registers it between the quickstart and add-to-existing-project entries,
and links it from the quickstart and the Prisma ORM landing page.

Every command and file on the page was run twice against a fresh
`create-db` database with prisma 8.0.0-rc.15 and @prisma/orm-postgres
8.0.0-rc.11; the hashes in the expected-output blocks are the real ones.

Closes #8203

declaration in both Prisma contract examples: the initial contract and the
updated contract in Step 6. Preserve the existing contract contents otherwise.
- Line 149: Update the PostgreSQL prerequisite text in the from-scratch guide to
require a new or disposable database and explicitly warn against using one
containing existing application data; retain the existing create-db guidance
unchanged.

Step 4 creates the tables and step 5 clears the User table on every run, so the prerequisite now says so. The contract examples carry the Prisma 8 marker when sibling pages do.
