# Editor

> Content, Resources and Strata, and Publish. The editor's three steps, and the checks that gate publishing.

Open the editor with **Create blueprint** on the dashboard, or by editing an
existing blueprint. The three steps can be visited in any order; only
publishing is gated.

## 1. Content

Title and tabs. The first tab must be a diagram.

The canvas fills most of the step. The engine menu switches between Vellum,
draw.io, Excalidraw and Mermaid; Vellum is the default unless you have changed
it in **Settings → General**.

Right-clicking a shape offers **Add Stratum…** here, so detail can be written
before the diagram is finished.

## 2. Resources & Strata

Everything alongside the diagram: strata, further diagrams that are not tabs,
and uploaded files organised into folders.

Skippable on a first pass.

## 3. Publish

> [!STEPS]
>
> === Review the suggested tags
>
> Generated from your content. Correct them: they drive discovery and the
> related-content rail.
>
> === Set visibility
>
> [Public, unlisted, or private](/foliums/blueprintr-user-guide/blueprints/publishing-and-visibility).
>
> === Clear the pre-flight checks
>
> Empty canvases, empty tabs and missing titles are blocked here rather than
> shipped. Each item in the list links to the thing to fix.
>
> === Publish
>
> Sets a version. Readers see that version until you publish again.

> [!TIP]
> **Preview** shows the reader's view without publishing, including strata and
> tab chrome. Use it before the first publish rather than after.
