The client needed a way to explain a complex concept - polkadot parachains - to an audience of largely non-technical, crypto-curious users and potential investors. Most existing explanations were jargon-heavy and hard to follow.
The challenge was to identify the key points that were necessary to understand, and identify a way to convey them without recourse to unhelpful and (to the reader) irrelevant detail.
The final article introduced the full concept of parachains, including related topics such as parathreads and Kusama, by using a series of analogies (e.g.a shopping mall, Lord of the Rings), with detailed engineering terms kept to an absolute minimum.
