With a filename.tar you have to do:
tar -xvf filename.tar
that should give you a directory like
filename/
change directory into that directory and there should be a README
file or a INSTALL file to show you how to install the app.
As a side note instead of doing gzip -d filename.tar.gz you could do this:
tar -xzvf filename.tar.gz
This will uncompress the file and un-tar it all in one command
