+# Contributing
+
+Thanks for improving this jQuery 4 cheat sheet. Keep changes factual, short, and useful for beginners.
+
+## Content Rules
+
+- Verify API behavior against official jQuery documentation before editing examples.
+- Use jQuery 4-safe examples.
+- Do not add removed APIs except inside the removed API section.
+- Prefer short examples that show one concept.
+- Use explicit CSS units in `.css()` and `.animate()` examples.
+- Mark each entry with one `jquery4Status`: `current`, `changed`, `removed`, or `caution`.
+- Include an official jQuery URL for every entry.
+
+## Data Format
+
+Edit `data/jquery-4-cheatsheet.json` for content changes.
+
+```json
+{
+  "id": "events-on",
+  "title": "Attach an event handler",
+  "syntax": ".on(events[, selector], handler)",
+  "example": "$(\".save-button\").on(\"click\", function () {\\n  $(this).text(\"Saving...\");\\n});",
+  "notes": ".on() is the main event API for current jQuery code.",
+  "jquery4Status": "current",
+  "replacement": "",
+  "officialUrl": "https://api.jquery.com/on/"
+}
+```
+
+## Checks
+
+Run:
+
+```bash
+npm run validate
+```
+
+Review the Pages site locally:
+
+```bash
+npm run serve
+```
+
+Open `http://localhost:4173` and check search, filters, copy buttons, dark mode, and mobile layout.
