tl;dr:“How we communicate” guidance, we established eight guiding principles: (1) Be asynchronous first. (2) Write things down. (3) Make work visible and overcommunicate. (4) Prefer GitHub tools and workflows. (5) Embrace collaboration. (6) Foster a culture that values documentation maintenance. (7) Communicate openly, honestly, and authentically. (8) Remember, practicality beats purity. The authors also detail how GitHub uses its own platform for planning, discussing, and documenting work.
