Status update:

• Draft of user guide, tutorial, and command line reference is at https://wikitech.wikimedia.org/wiki/User:Triciaburmeister/Sandbox/requestctl
• Draft of overview is at https://wikitech.wikimedia.org/wiki/Requestctl/Overview

I ended up working on the improving the content and style of these docs, not just their structure. I just couldn't effectively work on the structure without understanding more of the content, and I couldn't resist improving the content when I was reading it for understanding. So! the scope of this task is slightly larger than originally defined, but the improvements are already underway and it'll be easier for @CDanis or whoever the final subject matter expert reviewer/writer is to fill in the gaps.

Items still TODO, some of which may require consultation:

• There are many TODOs in the drafts, some of which I will resolve but others will require SMEs to fix.
• I'm not sure we'll end up keeping the layout grid for providing navigation between these 3 pages. For the user guide, tutorial, and reference content, I've chosen (for now) to do a single-page model, which is best for ctrl+f and panicked on-call searching, but may not be the best overall since the TOC and page are already quite long. The tutorial can be moved elsewhere if the user guide covers all the tasks and commands that were previously only covered by the tutorial.
• To build out this content, I copied everything from the README and integrated it with the content that was on the wiki page. We need to decide where we want the content to live, and implement the necessary cross-references (right now the drafts are duplicating content that is in the README).
• There are multiple developer tasks and pieces of information I identified during the research phase of this project; we still need to add those to the pages, and compare the content of the DDoS playbook to check for coverage of content there vs in these docs.
• Need to clarify what the intended functionality of the web app / new requestctl UI (T371782) will be, and how that impacts what the docs need to cover.

Thanks to @Joe for work on building out the tutorial content for haproxy actions, and addressing various TODOs from my first drafts. I have finished revising, copy-editing, and cleanup of both:

• User guide and command-line reference: https://wikitech.wikimedia.org/wiki/User:Triciaburmeister/Sandbox/requestctl
• Overview / concepts: https://wikitech.wikimedia.org/wiki/Requestctl/Overview

We agreed to move the tutorial content into its own page because there was too much: https://wikitech.wikimedia.org/wiki/Requestctl/Tutorials. I will review and copy-edit that tomorrow, and plan to move the user guide from my sandbox to the mainspace at https://wikitech.wikimedia.org/wiki/Requestctl tomorrow or on Monday.
