+## Getting Started

+Just type your message and press Enter (or Ctrl+Enter in Ctrl+Enter mode).
+
+## Tips

+- **Sessions** — your conversation history is preserved. Use the Sessions panel to revisit old chats.
+- **Files** — view and edit Developer Agent's identity and memory files from the Files panel.
+- **Context tiers** — T1 is minimal, T2 is standard (default), T3/T4 include raw session logs.
+- **Memory** — Developer Agent's memory is distilled automatically. You can trigger it manually via ⚙ → Distill.
+- **Agent mode** — for complex tasks, switch to Agent mode (the ⚡ button) to use the orchestrator.
