Note: This version of the VDT (1.3.9) is no longer supported. Feel free to look through the documentation and install it, but we cannot guarantee support for it. The current stable release is 2.0.0.

Installing the VDT

Create the root directory of the VDT install. Some common choices are /opt/vdt for root installs and ~/vdt for user installs.
```
> mkdir /opt/vdt
> cd /opt/vdt
```
If you're running behind a web proxy, tell Pacman about it.
Pacman will ask if you want to start a new installation in the current directory. Answer 'y' if the directory is correct.
```
> pacman -http-proxy:http://proxy.server:port
```
Install the VDT.
Pacman will ask you several questions. If you didn't set up a web proxy, Pacman will ask if you want to start a new installation in the current directory. Answer 'y' if the directory is correct. It will also ask you to trust the VDT cache. Answer 'y' or you won't be able to install the VDT.
This example installs the full VDT. If you chose to install a subset of the VDT, use that package name instead.
```
> pacman -get http://vdt.cs.wisc.edu/vdt_139_cache:VDT
Do you want to add [http://vdt.cs.wisc.edu/vdt_139_cache] to [trusted.caches]? (y or n): y
Package [VDT] found in [http://vdt.cs.wisc.edu/vdt_139_cache]...
Package [VDT-Common] found in [http://vdt.cs.wisc.edu/vdt_139_cache]...
Package [VDT-Core] found in [http://vdt.cs.wisc.edu/vdt_139_cache]...
...
```
You'll see a lot of output as Pacman fetches the necessary files. Don't get up and leave just yet.
Answer the VDT's questions.
After fetching the source files, Pacman will ask you to accept the licenses for the software included in the VDT. VDT software comes with a variety of licenses, including the GPL and several BSD variants. None of these licenses govern how you use the VDT, but some may effect redistribution and how you choose to link with VDT software. You must accept the licenses and answer 'y' to install the VDT.
```
VDT 1.3.9 installs a variety of software, each with its own license.
In order to continue, you must agree to the licenses.
You can view the licenses online at:

     http://vdt.cs.wisc.edu/licenses/1.3.9/

After the installation has completed, you will also be able to
view the licenses in the "licenses" directory.

Do you agree to the licenses? [y/n] y
```
After you agree to the licenses the VDT may ask additional questions depending on what user is doing the install and which components you selected. If you're not sure how to answer you can always choose skip and do any configuration later. Instructions will be placed in $VDT_LOCATION/post-install/README.
Take a break. The VDT installation will finish in the next 10-15 minutes (for a full installation) without any more user input. When it's done, Pacman will stop quietly, with no fanfare. Congratulations! You have installed the VDT.
Before you run any code from your new VDT, you must setup your environment. This example assumes you're using the Bourne shell or Bash. If you're using the C shell you should source setup.csh instead.
```
source setup.sh
```

Now that the VDT is installed and set up, you can take care of any optional post-install steps to configure additional software.
