-All source files except those in `devices`, `flags`, `searchEngines` and `socials` need to have a second file called `iconname.ext.source` that mentions where the image is from.
+🖌️ Hint: We regularly generate a [list of improvable icons](https://app.travis-ci.com/github/matomo-org/matomo-icons). Some may have the wrong source file format, some may be too small. Feel free to pick one or two and provide a PR for it.

+All source files are stored in categorized subfolders in `/src`.
+Please check whether your icon proposal complies with the following conventions. Then run the `convert.sh` script once to update the icon build in the `/dist` folder.
 
 ### File Formats
 
-Ideally all source files should be SVGs or high resolution (>100px) PNGs. As this is not always possible, JPGs, GIFs and (even multiresolution) ICOs are supported.

+### Naming
+
+The grouping and naming of all icons results from the data sets that Matomo uses in its own tracking analysis.
