-You can test that `kloak` actually works by trying an [online keystroke biometrics demo](https://www.keytrac.net/en/tryout). For example, try these three different scenarios:
+Consider these three different scenarios:
 * Train normal, test normal
 * Train normal, test kloak
 * Train `kloak`, test `kloak`
 
-*Train normal* means to train with normal typing behavior, i.e., without `kloak` running. At the enrollment page on the KeyTrac demo, enter a username and password without `kloak` running, and then on the authenticate page, try authenticating. For example, the train normal/test normal result is:
