 | [`stack/`](stack/) | **The templates.** Ten numbered sections — company, customer, market, product, GTM, operations, money, capital, brand, pulse — one markdown file each, with front matter. [`stack/INDEX.md`](stack/INDEX.md) is the router an AI reads first, and [`stack/CONTEXT.md`](stack/CONTEXT.md) is the one-pager it reads next. This *becomes* your knowledge base; you fill it in, you do not copy it out. |
 | [`prompts/`](prompts/INDEX.md) | **The prompt library.** 19 prompts: bootstrap, gap scan, competitive intelligence, unit economics, the list of 100, the pitch deck, fundraise readiness, the weekly recap, meeting-to-actions, and the adversarial review that tells you what an investor will attack. Each opens with a `Requires:` line and stops if what it needs is missing. Most want a filled-in stack; [`00`](prompts/00-bootstrap-the-stack.md), [`14`](prompts/14-meeting-to-actions.md) and [`15`](prompts/15-scrape-a-site.md) run against an empty one, which is how a stack starts to fill. The last three belong to `portfolio/` and never touch a founder's stack. |
 | [`worksheets/`](worksheets/) | **The repeatable artifacts.** Fill-in files you produce over and over: startup-prep, customer interview, competitor profile, two-week experiment, SOP entry, trade/order sheet, advisor scope letter, one-pager, list of 100, weekly recap. |
-| [`docs/`](docs/) | **The method, in twenty-four pages.** New to any of this: [AI basics](docs/ai-basics.md) and [what the words mean](docs/what-things-are.md) — the terminal, an editor, Git, GitHub, connectors, model tiers — each in plain language with a diagram. The method: [why it works](docs/method.md), [building the knowledge base](docs/knowledge-base.md), [the front-matter schema](docs/front-matter.md), [getting your material in](docs/getting-material-in.md) source by source, and [website to inbox](docs/scraping.md). Running it: [the weekly recap](docs/weekly-recap.md), [for coaches](docs/for-coaches.md), [the safety rules](docs/safety.md) for giving an AI access to your files, and [on a schedule](docs/automation.md) — recipes for Microsoft 365, Google Workspace, Zoom, Slack, and none of them. Two are for programmes only: [for programmes](docs/for-portfolios.md) and [the exchange folder](docs/exchange.md). And [the infographics](docs/infographics.md) — thirty pictures across four pages, covering [what AI is](docs/infographics-ai.md), [the tools](docs/infographics-tools.md), [the method](docs/infographics-method.md) and [running a portfolio](docs/infographics-portfolio.md); take them for a workshop. Last, [startup resources](docs/resources.md) — 92 external articles, templates and videos worth reading, credited to their publishers and grouped across six pages. |

 | [`portfolio/`](portfolio/) | **Optional — for a programme, not a founder.** The templates an incubator, accelerator or studio uses to run this across many companies: a router, a 1-to-5 maturity rubric per function, the cross-company theme scan, and a company folder to copy. Delete it if you are a founder. See [docs/for-portfolios.md](docs/for-portfolios.md). |
 | [`_inbox/`](_inbox/) | Where raw material lands before it is processed. Git-ignored by default. |
 | [`tools/`](tools/) | **Optional.** [`scrape-site.mjs`](tools/scrape-site.mjs) turns a website into citable markdown in `_inbox/` — you never need it, it saves an hour of copy-and-paste ([docs/scraping.md](docs/scraping.md)). [`make-og.mjs`](tools/make-og.mjs) redraws the social card at the top of this page; run it if you fork and rename. A third tool lives in its own repository: [**site2deck**](https://github.com/fritzhand/site2deck) samples a company's colours, fonts and logo off its website and builds a branded, offline, single-file slide deck — the object to put in front of a room once [prompt 10](prompts/10-pitch-deck.md) has written what goes in it. Same habits as this repo: zero dependencies, Node only, unknowns marked loudly rather than filled in, and a `--public` build that strips anything tagged internal and refuses to ship if one survives. |
