brain dump

n. [common] The act of telling someone everything one knows about a
particular topic or project. Typically used when someone is going to let a
new party maintain a piece of code. Conceptually analogous to an operating
system core dump in that it saves a lot of useful state before an exit.
You'll have to give me a brain dump on FOOBAR before you start your new job
at HackerCorp. See core dump (sense 4). At Sun, this is also known as TOI
(transfer of information).
