 The example above represents the minimal tweaking necessary to get Agate
-up and running.  Specifying the path to the certificate and key is
+up and running.  Specifying the path to the certificate and key directory is
 always necessary, as the Gemini protocol requires TLS by default.
 
-To obtain a certificate and a key, you could, for example, use OpenSSL,
-running a command similar to the following example:
+If specified path is writable by Agate, and contains no valid key
+and certificate, the Agate will try to generate them on the first start.
+If specified directory is read-only - key and certificate should be 
pre-generated by user.
+
+To obtain a certificate and a key in a DER format, you could, for example,
+use OpenSSL, running a commands similar to the following example:
 
 @example
-openssl req -x509 -newkey rsa:4096 -keyout key.rsa -out cert.pem \
-    -days 3650 -nodes -subj "/CN=example.com"
+openssl genpkey -out key.der -outform DER -algorithm RSA \
+    -pkeyopt rsa_keygen_bits:4096
+openssl req -x509 -key key.der -outform DER -days 3650 -out cert.der \
+    -subj "/CN=example.com"
 @end example
 
 Of course, you'll have to replace @i{example.com} with your own domain
 name, and then point the Agate configuration towards the path of the
-generated key and certificate.
