initialise
Prepare for use
Initialise is the British spelling of initialize, meaning to set something to its starting state or prepare it for use.
The term appears most often in computing contexts, where you initialise variables, arrays, or systems before they can function properly: The program failed because the array wasn't initialised.
More broadly, it can mean to begin or set up any process or system from scratch.
