 ## OpenKeychain specific
 We try to provide a better terminology when we think that the traditional one is flawed:
 * identities instead of user ids
-* instead of "certify keys", we speak of "certify identities", german: "beglaubige Identitäten"
+* instead of "certify keys", we speak of "certify identities", german: "beglaubige Identitäten" (that's what you are doing: certify identities, not the key (nobody understands the abstract definition of key))
 * don't speak of public and private keys, only keys (only in rare circumstances: private key?)
