Then I got here just in time!
On Dec, 14, 2016, I'll be presenting an STC webinar on my tips for planning an API documentation set. While the webinar was developed for technical writers who are new to API documentation, it might also provide some new insights for experienced writers.
In the webinar, I talk about how to understand the API audience, market, and the API itself to plan and prioritize what you write for your API. For more info and to sign up, see https://www.stc.org/event/plan-api-documentation-understanding-audience-market-product/
Hope to see you online!
