These are generic installation instructions, because dcd is a generic program.

* Look at the Makefile.
  There are a few things you might want to change:
  * By default, dcd installs in to ~/bin which you may not like.
  * If /dev/cdrom isn't a symlink to your "real" CD-ROM device, either edit
    the Makefile or create the symlink as appropriate.
  * There are two definitions of CFLAGS - one for debugging (which is
    commented out by default) and one for actual use.
  * Various other configuration options which are explained much better
    in the Makefile. 

* Type make. Optionally, follow that up with a "make install."
