EA Organisations: If you created a sequence about your approach to doing good, what would you write?

I've recently started interning with Charity Entrepreneurship have been reading some key articles that I found really useful to understanding the organisation better and to actually do the work I've been doing better, such as:

• Reasoning Transparency
• Sequence vs Cluster Thinking
• CE's research process, and the reasoning behind it.

I'd be curious if other EA organisations have some "must-read" articles that encapsulate the organisation's approach to doing good - the high level strategy, assumptions about welfare or suffering, perspective on the future, theory of change or anything else.
