+\title{RKorAPClient: 'KorAP' Web Service Client Package}
+\description{
+
+A client package that makes the 'KorAP' web service API accessible from R.
+  The corpus analysis platform 'KorAP' has been developed as a scientific tool to make
+  potentially large, stratified and multiply annotated corpora, such as the 'German Reference Corpus DeReKo'
+  or the 'Corpus of the Contemporary Romanian Language CoRoLa', accessible for linguists to let them verify
+  hypotheses and to find interesting patterns in real language use.
+  The 'RKorAPClient' package provides access to 'KorAP' and the corpora behind it for user-created R code,
+  as a programmatic alternative to the 'KorAP' web user-interface.
+  You can learn more about 'KorAP' and use it directly on 'DeReKo' at <https://korap.ids-mannheim.de/>.
