- Drop "one-click install" framing in README and explanation page; setup is
multi-step but consistent across the shelf.
- Drop "two files (sometimes three)" claim; honestly name SKILL.md,
INSTRUCTIONS.md, and any required data files (templates, CSVs,
validation checklists).
- Add explicit setup pattern in README (create Gem/GPT, upload knowledge,
paste instructions, save).
- Add "Updating and customizing" section to the explanation page covering
re-upload-the-attachments updates and the rule of thumb that custom
changes belong in the pasted instructions block, not the knowledge
files, so future updates don't clobber team customizations.
