+## Why
+
+The one other implementation [davechild/textstatistics](https://packagist.org/packages/davechild/textstatistics)
+sadly only implements statistics for english texts. That sadly didn't work for texts with
+f.e. german umlauts. So I decided to implement some of the algorithms again using work I
+already did for a [hyphenator](https://packagist.org/packages/org_heigl/hyphenator).
+
+That's why f.e. the syllable-calculation differs.
