+# Add a GPhoto2 Camera Profile
+
+This guide shows how to add support for a new gphoto2-compatible camera using a
+Python profile class.
+
+## 1. Detect your camera
+
+Connect camera over USB and run:
+
+```bash
+gphoto2 --auto-detect
+```
+
+Copy the detected model string. You will use parts of this string in
+`_MODEL_MARKERS`.
+
+## 2. Inspect config keys and choices
+
+List available keys:
+
+```bash
+gphoto2 --list-config
+```
+
+Inspect important keys:
+
+```bash
+gphoto2 --get-config /main/settings/capturetarget
+gphoto2 --get-config /main/capturesettings/shutterspeed
+gphoto2 --get-config /main/imgsettings/imageformat
+gphoto2 --get-config /main/imgsettings/iso
+```
+
+## 3. Copy the template profile
+
+Copy:
+
+`openscan_firmware/controllers/hardware/cameras/gphoto2/profiles/template_camera.py`
+
+Create a new file with your camera name, for example:
+
+`openscan_firmware/controllers/hardware/cameras/gphoto2/profiles/my_camera.py`
+
+Then update:
+
+- `profile_id`
+- `_MODEL_MARKERS`
+- config key lists (`_SHUTTER_KEYS`, `_ISO_KEYS`, `_RAW_FORMAT_KEYS`, ...)
+- startup defaults in `apply_startup_config`
+- optional RAW behavior in `capture_dng`
+
+## 4. Register the profile
+
+No manual registry edit is needed.
+
+All Python modules in:
+
+`openscan_firmware/controllers/hardware/cameras/gphoto2/profiles/`
+
+are auto-discovered by the profile registry at startup.
+
+Requirements:
+
+- your class must inherit from `GPhoto2Profile` (or `GenericGPhoto2Profile`)
+- `register_in_registry` must be `True` (default)
+- `matches(identity)` should return `True` only for your target camera model
+
+## 5. Run a JPEG test
+
+Use the firmware API/flow to capture a JPEG and check:
+
+- image is captured successfully
+- expected shutter and quality values are applied
+- diagnostics show expected config keys
+
+## 6. Run a RAW test
+
+Capture RAW/DNG via the firmware flow and verify:
+
+- file extension is RAW-like for your camera (`.nef`, `.cr2`, `.raw`, ...)
+- profile can switch to RAW mode
+- profile restores previous image format after capture
+
+## 7. Debug setting failures
+
+`write_first_config(...)` returns explicit result details:
+
+- attempted keys
+- requested value
+- success/failure
+- failure message
+
+If a setting fails, inspect these values first, then compare with
+`gphoto2 --get-config <key>` output.
