+* BER/CER/DER decoding, DER encoding
 * Basic ASN.1 data types (X.208): BOOLEAN, INTEGER, BIT STRING, OCTET
-  STRING, NULL, OBJECT IDENTIFIER, ENUMERATED, all strings, UTCTime,
-  GeneralizedTime, CHOICE, ANY, SEQUENCE (OF), SET (OF)
+  STRING, NULL, OBJECT IDENTIFIER, ENUMERATED, all strings, UTCTime (no
+  BER), GeneralizedTime (no BER), CHOICE, ANY, SEQUENCE (OF), SET (OF)
 * Size :ref:`constraints <bounds>` checking
 * Working with sequences as high level data objects with ability to
   (un)marshall them
-* Python 2.7/3.5 compatibility
+* Python 2.7/3.5/3.6 compatibility

 * No old Python versions support
-* No BER/CER support
-* PyDERASN does **not** have object recreation capable ``repr``-s::
