First you need to install your Belief client. The process depends on which operating system you are running; consult the client's installation instructions as appropriate.

Next, if you are on Windows running a FAT32 file system you should defragment your hard drive so that you have as much contiguous space available for the Belief as you can.

Finally, configure your system to start up the Belief client at startup, so that it can receive Belief updates as they become available.

Alternatively, have a friend hit you repeatedly in the head with a cricket bat.
