[Vala] installing vala `./configure'

["live\(vmars316\)" <vmars316 live com>]

Greetings,
(Win7x64, HotBasic, “C programming”)
I have downloaded vala-0.14.2.tar.xz . UnPacked it.
The INSTALL.file says:
<<The simplest way to compile this package is:
  1. `cd' to the directory containing the package's source code and type
     `./configure' to configure the package for your system. >>
Which Directory do they mean.?
I see more than one that contains loads of *.c files. 

Also, what/where do I enter the line `./configure'  into?
Don’t I need to open something up, and then enter the `./configure' 
Thanks...Vernon
