#50 The guide: ChatGPT builds from the archive kept in a Project

Closes #49.

The guide told people using ChatGPT to attach h5p-author-build.tar.gz to the message where they ask, in every chat. On the owner's free account, on 2026-11-14, the archive kept in a ChatGPT Project built a Question Set in a chat of that project, and the package passes the verifier.

What changes

• The guide's install step (/h5p/create-with-ai/): for ChatGPT, make a Project, add the archive to it, and ask in a chat of that project; outside a project, attach it to the message.
• Its step on getting the file, and the help entry The chat says it cannot get the build tool: the same, in a clause each.
• The build page's third step and the README: "kept in a Project or attached".

Before merging

This rests on one run. Two things are worth confirming first:

• that the archive was added to the Project's own files, and not attached to the message of a chat in it;
• that a second, new chat of the same project builds with nothing attached.

It is a draft until then.

Checks

• pnpm build passes in the branch: tsc, Eleventy and Vite.
• The four changed passages were read as the built pages show them.

The rule and what was measured are in design/author.md of h5p-offline-player, with missing-elements/h5p-offline-player#203.

Summary by cubic

Updates the ChatGPT instructions in the guide, build page, and README so the build archive can be kept in a ChatGPT Project and used from chats within it, instead of attaching h5p-author-build.tar.gz to every message.

• Documents the Project workflow as the first option and attaching the archive as the fallback outside a Project.
• Revised passages: install step, get-the-file step, help entry, build page third step, README.
• Draft until confirmed that the archive was added to the Project's own files and that a new chat in the project builds with nothing attached.
