+Pull requests run **`npm run format:check`** (Prettier against `.prettierrc` and `.prettierignore`). Run
+**`npm run format`** locally to fix style before pushing. Generated Snaps API pages under
+`snaps/reference/snaps-api/` are excluded from formatting in git (see `.prettierignore`).

 Pull requests are checked by a Vale-based linter
 ([docs-spelling-check](https://github.com/Consensys/github-actions/tree/main/docs-spelling-check))
 that enforces Microsoft style, Consensys terminology, and spelling. Fix any linter warnings before

 ## Code blocks
 
 - Always specify the language on fenced code blocks (` ```javascript `, ` ```bash `, etc.).
-- Use double quotes in JavaScript code samples.
 - Indent code with two spaces, not four.
+- In JavaScript, TypeScript, JSX, and TSX samples, use single-quoted string literals.
+- In JSON samples, keep double-quoted keys and strings (required by JSON syntax).
+- In any other language (for example, Swift, Kotlin, Dart, Solidity, Python, shell), follow that
+  language's normal conventions for string quotes.
+- After editing documentation, run `npm run format` so Prettier applies these rules to fenced code
+  in Markdown/MDX (see `.prettierrc`).
 - For npm install commands, use ` ```bash npm2yarn ` fences to produce automatic npm/yarn tabs.
 - Write code samples that can be copied, pasted, and run as-is. Do not include shell prompts
   (for example, `user@host $`) or trailing comments that break execution.
