 # korapxmltool
 
-Tool package to convert and annotate KorAP-XML ZIP files.
+Converts between KorAP-XML ZIP format and formats like CoNLL-U, Krill, word2vec, NOW and annotates KorAP XML ZIPs with various taggers and parsers.
 
-Up to 200 times faster and more accurate drop-in replacement for the korapxml2conllu part of [KorAP-XML-CoNLL-U](https://github.com/KorAP/KorAP-XML-CoNLL-U).
+Drop-in replacement for korapxml2conllu [KorAP-XML-CoNLL-U](https://github.com/KorAP/KorAP-XML-CoNLL-U) and korapxml2krill [KorAP-XML-Krill](https://github.com/KorAP/KorAP-XML-Krill)
 
-For some conversion tasks, however, you currently need the conllu2korapxml part of [KorAP-XML-CoNLL-U](https://github.com/KorAP/KorAP-XML-CoNLL-U).
