+GENERAL INFORMATION
+===================
+
+The SAE J2735-201603 Dedicated Short Range Communications (DSRC)
+Message Set Dictionary decoder.
+Invoking `make` will compile the ASN.1 specifications from the
+../J2735_201603.asn1 file.
+
+THERE IS NO J2735_201603.asn1 FILE THERE YET!
+
+OBTAINING THE J2735 SPECIFICATION
+=================================
+
+Go to http://standards.sae.org/j2735_201603/ and download the files.
+
+You should extract the ASN.1 module from there and save it
+as the ../J2735_201603.asn1 file. This file should start with
+the following line
+
+ DSRC DEFINITIONS AUTOMATIC TAGS ::=
+
+and end with the "END" token.
+Be careful not to copy any non-ASN.1 preambles from that .DOC file.
+
+After obtaining the J2735_201603.asn1, type `make` in the directory
+containing this README file.
+
