 ## Requirements
 
-- **Node 22**
-- **npm**. Yarn/pnpm are great, but please stick to npm so lockfiles stay in sync.

 - **Docker** (optional)

 5. Sync Prisma with the database:
    ```bash
-   npx prisma db push   # creates tables
-   npx prisma db seed   # seeds languages, files and snippets
+   bunx prisma db push   # creates tables
+   bunx prisma db seed   # seeds languages, files and snippets

 ## Pull request checklist
 
 - Create a branch off `main` with a descriptive name (`feature/auto-closing-tweak`, `fix/language-picker`, etc.).
 - Keep changes scoped. Smaller PRs get reviewed faster.
 - Update docs when behavior changes (README, this file, inline comments).
-- Run `npm run lint`, `npm run prettier`, and `npm run build` locally.
+- Run `bun run lint`, `bun run prettier`, and `bun run build` locally.
 - Include screenshots or screen recordings if you touch UI/UX. A quick Loom/GIF helps reviewers verify the behavior without pulling the branch immediately.
 - Push your branch and open a PR against `main`. Describe the problem, your solution, and any follow-up work you’re leaving for later.
