# Where This Came From

Fuse Lab did not invent every useful idea in this handbook. Some ideas have been with us since our earliest culture work, some came from things we learned the hard way, and some were adapted from companies whose documentation we respect.

These are references, not scripture. We should steal good ideas with credit, adapt them to the reality of Fuse Lab, and discard them when they stop helping.
