1. Unzip and unrar to a temp directory
2. Run "tar -xzvf houdini-8.1.655-replace_by_ver.tar.gz" (without the "")
   Run "./houdini.install" (without "") and follow instructions ..

3.Before Starting Houdini, you must first set up the shell environment.
  At a C shell prompt (csh, tcsh, bash), type the following:

        source houdini_setup (for csh/tcsh)
	source houdini_setup_bash (for bash/zsh)

This command initializes the current shell's environment to run
Houdini.  You may want to add the above line to your .login file.

4.Licensing:
  Launch the License Administrator by typing "hkey".
  In the Server Information you will find your Server Name & Server Code
  
  Launch the Win32 Houdini Keygen or the Linux keygen 
  Enter your Server Name & Server Code 
  (those can also be obtained this way : /usr/lib/sesi/sesictrl -n)
  and generate your license keys ...

  Go back to the License Administrator 
  Select File/Manually Enter Keys...
  Copy paste the keys you generated 5 by 5 .
  Key string #1 should be SERVER your_server_name server_code ..... 

NB : Install the "other keys to play with" at your own risk, those are mainly
     for dev and debug ... so Make sure you installed the License keys first

5.  To start Houdini Master, type "houdini".
    To start Houdini Select, type "hselect".
    To start Houdini Halo,   type "hhalo".



NB: you can install either a 8.1 or 8.2 license . it is all the same,just fancy
