 Features
-========
+--------
 
 Currently this library implements parsing/decryption and encoding/encryption
 of TR-31 format version A, B, C, and D. Various helper functions are also
 available to stringify TR-31 header attributes.
 
 Dependencies
-============
+------------
 
 * C11 compiler such as GCC or Clang
 * CMake
 * TR-31 library requires MbedTLS (preferred), or OpenSSL
 * TR-31 tool requires argp (either via Glibc or a standalone implementation)
 
 Build
-=====
+-----
 
 This project uses CMake and can be built using the usual CMake steps.
