This document discusses the value of free and open source software (FOSS) and provides guidance on how to successfully integrate it. It notes that FOSS code is flexible and allows anyone to join in building shared platforms that work better. While some lawyers may not fully understand FOSS, following the terms of licenses and resolving any issues through good faith can help leverage FOSS and share value with the community in a sensible way. The key is to decide which license approach works best while letting engineers explore the code and working with other groups to reduce overlap.
