+description: The one space in this demo where you may write — try the editor, reviews and diagrams here.
+tags: [playground]
+lang: en
+---
+
+# Playground
+
+This space is yours to try things out. Everything else in this demo is
+read-only; here you can create pages, edit them, open a review and approve
+it — the full workflow from the [User Guide](https://github.com/rotecodefraktion/f451/tree/main/demo/user-guide).
+
+> [!NOTE]
+> The demo is reset every night. Whatever you write here disappears then.
+
+## Things to try
+
+1. Click **Edit** on this page, change a sentence and save.
+2. Type **/** in the editor and insert a callout, a draw.io diagram or an
+   Excalidraw sketch.
+3. **Request review**, then **Approve & merge** — and look at the pull request
+   that appeared in Forgejo.
+4. Create a new page with **+** in the sidebar, from the **Process runbook**
+   template if you like.
