-If you already have your rsa keys, skip this step. If you are new
-to paraslash, you have to generate an rsa key pair for each user you
-want to allow to connect. You need at least one user.
+Note that the RSA keys for paraslash 0.3.x will not work for version
+0.4.x as the new version requires stronger (2048 bit) keys. If you
+already have your 2048 bit keys, skip this step. If you are new to
+paraslash, you have to generate a key pair for each user you want to
+allow to connect. You need at least one user.
