+## 📝 Problem Description
+<!-- A clear description of the bug or the feature you'd like. -->
+
+## 🚦 Current Behavior
+<!-- What actually happens today. For feature requests, describe the current limitation. -->

+## 🎯 Expected Behavior

+
+## 📋 Steps to Reproduce
+<!-- If it's a bug, how can we reproduce it? -->
+1.
+2.
+3.
+
+## 📡 Radio Node
+<!-- The MeshCore radio RemoteTerm is talking to. -->
+- **Firmware version:** <!-- e.g. 1.15.0 -->
+- **Hardware / board type:** <!-- e.g. Heltec V3, RAK4631, T-Deck -->
+
+## 🔌 Connection to the Radio
+- **Connected directly to the radio, or through an intermediary?**
+  <!-- Direct is the only officially supported path. If you use an intermediary
+       companion/frameserver such as pyMC / OpenHop, please say so — many issues
+       are specific to those and won't reproduce on a direct connection. -->
+- **Transport:** <!-- Serial / TCP / BLE -->
+
+## 💻 Environment Information
+- **OS:** <!-- e.g. macOS 15, Windows 11, Raspberry Pi OS -->
+- **Browser / Version:** <!-- e.g. Chrome 150, Safari 18 -->
+- **RemoteTerm Version:** <!-- e.g. v3.15.2, or "wrapped" HA add-on -->
+
+## 📸 Screenshots / Debug Logs
+<!-- Screenshots are great. For bugs, a debug snapshot or debug-level logs help enormously. -->
+
+<details>
+<summary><b>How to attach debug information</b> (please read — it speeds up diagnosis a lot)</summary>
+
+**Easiest — debug support snapshot (recommended for everyone):**
+In the app, go to **Settings → About → "Open debug support snapshot"** (or navigate to
+`/api/debug`). Copy the block and paste it here.
+
+> 🔒 The snapshot includes recent logs and basic environment/radio status. It never
+> exposes your private key. Logs *may* contain channel names or keys. If you'd rather
+> not share those, copy only **up to the `STOP COPYING HERE` marker** — everything
+> above it reveals nothing sensitive beyond your bot names.
+
+**Advanced — full debug-level logs:**
+Restart the backend with debug logging enabled to capture detailed radio
+communication and packet processing:
+```bash
+MESHCORE_LOG_LEVEL=DEBUG uv run uvicorn app.main:app --host 0.0.0.0 --port 8000
+```
+Then reproduce the issue and paste the relevant log output.
