How are you documenting your ETL processes

I'm currently using SSIS on a fairly large project. I wanted to know how
other developers are documenting their ETL processes. I've started using
Visio for flow charting some of my ETL processes. But I am finding it
difficult to use.
So, What tools/products are you using and are they working for you.
Thanks,
GHC.
