 - `qrfirst` or `textfirst`: switch position of QR-Code and text block, default: `qrfirst`
 - `https` or `www`: should links in the hints be prefixed with `https://` or `www.`, default: `https`
 - `countryformat=`: how to format the country in address. Values: `auto` (default: inline with mdash if <4 chars and city/zip exists), `inline` (always inline with mdash), `below` (always separate line)
-- `qreclevel=`: QR error correction level `L` (~7%), `M` (~15%), `Q` (~25%), or `H` (~30%), default: `Q`. Use `H` when `photoinqr=true`.
-- `photoinqr` or `nophotoinqr`: place photo in the center of the QR code (`photoinqr`) instead of next to the name, default: `nophotoinqr`. **Requires `qreclevel=H` for reliable scanning**.
-- `qrlogoscale=`: photo size in QR code as fraction of QR width (1.0 = 100%), default: `0.25` (25% width). Recommended values: Level H: 0.25-0.3, Level Q: 0.2, Level M: 0.15, Level L: 0.1. Higher values may reduce scannability.
-- `qrlogoborder=`: transparent padding around photo in QR code as fraction of QR width (1.0 = 100%), default: `0.02` (2%). Adds space between photo and QR modules.
-- `photoscale=`: scale factor for photo next to name (1.0 = 100% of name height), default: `1.0`. Use values like `2.0` or `2.5` for larger photos.
+- `qreclevel=`: QR error correction level `L` (~7%), `M` (~15%), `Q` (~25%), or `H` (~30%), default: `Q`. Use `H` when `logoinqr=true`.
+- `logoinqr` or `nologoinqr`: place logo in the center of the QR code (`logoinqr`) instead of next to the name, default: `nologoinqr`. **Requires `qreclevel=H` for reliable scanning**.
+- `qrlogoscale=`: logo size in QR code as fraction of QR width (1.0 = 100%), default: `0.25` (25% width). Recommended values: Level H: 0.25-0.3, Level Q: 0.2, Level M: 0.15, Level L: 0.1. Higher values may reduce scannability.

+- `logoscale=`: scale factor for logo next to name (1.0 = 100% of name height), default: `1.0`. Use values like `2.0` or `2.5` for larger logos.
 - `bgscale=`: background image scale factor (1.0 = 100% of card height), default: `1.0`. Use values like `1.5` or `2.0` for zoomed/cropped backgrounds. Only affects images, not colors.
 - `bgopacity=`: background image opacity/transparency (1.0 = 100% visible, 0.0 = invisible), default: `1.0`. Use lower values like `0.2` or `0.3` to fade the background so text remains readable. Only affects images, not colors.
 - `qrbgopacity=`: QR code background opacity (1.0 = solid white, 0.0 = transparent), default: `1.0`. White background behind QR code ensures scannability over background images. Use `0.0` for no background or lower values like `0.8` for semi-transparent.

+**Important:** When using `logoinqr=true`:
 - Always use `qreclevel=H` (highest error correction ~30%) for reliable scanning
 - Test QR code scannability with multiple apps before printing
 - Default `qrlogoscale=0.25` (25% width = 6.25% area) is recommended for Level H
 - If scanning fails, reduce to `qrlogoscale=0.2` or `qrlogoscale=0.15`
 - PNG transparency is preserved - use images with transparent backgrounds for best results
