1.  These instructions assume you have a working version of [OpenFOAM-2.4.0](http://www.openfoam.org/archive/2.4.0/download/source.php).  If you are using Ubuntu 14.04 or greater, the installer will download and install the proper version of OpenFOAM in steps 8-10.  See the table below for the correct version of OpenFOAM required for HELYX-OS.

2.  Download the latest 64 Bit binary from step 1 above or from the [project front page](http://engys.github.io/HELYX-OS/).  The installer name will have the form:

        <date>-Engys-HELYX-OS-<version>--linux-x86_64-FULL.bin

3.  Once the binary is downloaded, open a Linux terminal and navigate through the terminal to the location of the newly downloaded HELYX-OS installer.

4.  Change the permissions of the installer by executing ```chmod 755 <installer name>``` in the terminal, similar to:

        :~$ chmod 755 20160114-Engys-HELYX-OS-2.3.1--linux-x86_64-FULL.bin

5.  Start the installer by typing ```./<installer name>``` while in the terminal, similar to:

        :~$ ./20160114-Engys-HELYX-OS-2.3.1--linux-x86_64-FULL.bin

6.  At this point, the installer will begin and the user will be guided through the installation process:

        Waiting for HELYX-OS installer to start...
    
        
        This program will install HELYX-OS on your system. Do you want to continue?
        1) Yes
        2) No
        #?
    
    In order to continue with the installation, you must type **1** in the terminal and press enter.<br>

7.  The user will be presented with a copy of the Gnu Public License (press enter or space to read through the GPL):

        Do you accept the terms of agreement?
        1) Agree
        2) Exit
        #?

    In order to continue with the installation, you must agree by typing **1** in the terminal and press enter.<br>

8.  Select which components to install:

        Select components to install
        1) HELYX-OS-GUI
        2) HELYX-OS-GUI and Kernel
        #?

    For users with existing installations of OpenFOAM (see compatability table above), select to install only the GUI by typing **1** and hitting enter.  To install the HELYX-OS GUI and the compatable version of OpenFOAM (for Ubuntu 14.04 or later only), type **2** and press enter. 

9.  The user will be prompted to enter **the full path** to where HELYX-OS will be installed:

        Select destination folder for HELYX-OS GUI:

    For example, if a user named Scott wants to install HELYX-OS to their home folder (this is the suggested location), then they woudl enter:

        Select destination folder for HELYX-OS GUI: /home/scott/
    
    and a folder named ```Engys```, containing HELYX-OS will be created in the user's home folder.  The GUI will install and produce the following output:

        Select destination folder for HELYX-OS GUI: /home/scott
        Installing in: /home/scott
        Installing HELYX-OS GUI ................done.

10.  If you previously selected option **2** in step 8, you will now be prompted to select your linux distribution:

            Please select your linux distribution:
            1) Ubuntu (14.04 or later)
            2) Other
            #?
    
        Selecting **1** will install the compatable OpenFOAM deb package for 64 bit Ubuntu on 14.04 or later.  For other linux distributions, the compatable version of OpenFOAM must be installed manually by the user.
    
11.  To start HELYX-OS in the terminal, execute the ```HELYX-OS.sh``` file located in ```engys/HELYX-OS/v2.3.1``` directory similar to:
    
            :~$ ~/Engys/HELYX-OS/v2.3.1/HELYX-OS.sh


Please report all bugs encountered with HELYX-OS on the [project issue tracker](https://github.com/ENGYS/HELYX-OS/issues).
