-# Translating the Basisklassifikation
+# Basisklassifikation WordPress plugin
+
+This is a WordPress plugin that provides a taxonomy for the so-called
+Basisklassifikation and an admin panel to upload JSKOS-files that contain
+a current version of that classificatory scheme.
+
+Note that processing a JSKOS file will likely take longer than PHP scripts are
+permitted to run on your server. WordPress has not been made to create
+thousands of taxonomy terms at once. You will need to adjust this limit before
+uploading a JSKOS file.
