+# Rstack docs writer
+
+Follow the project's existing documentation conventions.
+
+## Writing
+
+- Explain user-facing behavior concisely, adding details and examples only when they help users configure or use the feature.
+- Keep common abbreviations such as `dev server`.
+- Keep documentation in sync across locales when changing content. Use English as the default language unless the project specifies another.
+- Use sentence-case headings.
+
+## Heading anchors
+
+- Prefer Rspress's default anchors for headings in the default locale; preserve intentional existing custom IDs.
+- Determine generated anchors from heading `id` attributes: run the project's docs dev command and inspect the rendered browser DOM, or run its docs build command and inspect the generated HTML.
+- Match headings in other locales to the default locale's anchors, using the project's locale mapping to pair pages. Add custom IDs where defaults differ; remove redundant IDs only if anchors stay unchanged.
+- Escape custom IDs in MDX: `## Localized heading \{#default-locale-anchor}`.
+- When anchors change, update corresponding IDs across locales and affected Markdown links and JSX `href` attributes. Check target pages before replacing hashes.
+- Check changed links against their target headings.
