# Custom QR Code design

#### Below are the steps to configure custom designed QR code

* A sample styling is available here, <https://github.com/Sunbird-RC/sunbird-rc-core/blob/main/services/certificate-api/configs/qr_code_config.json>
* Once the styling file is added, the file needs to be mounted to `certificate-api` service as below

```
certificate-api:
    image: ghcr.io/sunbird-rc/sunbird-rc-certificate-api:latest
