+The project contains a set of flag icons generated using the "Noto Color Emoji" font on a Debian system, in the `/webassets/img/flags/` directory.
 
 The software uses a number of Python libraries as listed in `requirements.txt`, and a number of JavaScript libraries such as jQuery, Leaflet and Bootstrap. This project would not have been possible without these libraries, so many thanks to their developers.
 
-Particular thanks go to QRZCQ country-files.com for providing country lookup data for amateur radio, and to the developers of `pyhamtools` for making it easy to use this data as well as QRZ.com and Clublog lookup.

 The project's name was suggested by Harm, DK4HAA. Thanks!
