+# esp32c5 — multi-target workspace
+
+| Path | Notes |
+|------|-------|
+| `ESP32-C5-J4CK3D` | ESP32-C5–centric project |
+| `esp-idf/` | Embedded Espressif IDF tree / helper checkout |
+| `mater/` / `slave/` | Paired sketches (inspect each tree for README) |
+
+## Build
+
+Activate **ESP-IDF** (`export.ps1` / `. export.sh`). From the project you intend to compile:
+
+```bash
+idf.py set-target esp32c5    # after confirming support in that project
+idf.py build flash monitor
+```
+
+Use the subdirectory’s **`sdkconfig`** / docs for PHY, partitioning, secure boot flags, etc.
