This is an informal reference document for myself. Depending on the amount of third party information available this may or may not be transformed into official documentation.
I used the following site for instructions on installing.
Documentation PDF available here http://www.dspace.org/1_5_2Documentation/DSpace-Manual.pdf starts on page 20.
Documentation does not cover pieces like installing the database so those details are listed below, just keep referring back to the DSpace doco as you go.
