# [jdbb] studio — help

> The studio's book factory turns a manuscript (.docx from your editor) into an EPUB and a print-ready PDF. These pages explain the client side: sending a manuscript, reading what Inspect found, building and downloading, and the style sheet.

Every page is also available as markdown by adding `.md` to its URL. Factory API reference: https://studio.jdbb.net/factory/api

## Start here

- [How the factory works](https://studio.jdbb.net/help/start-here.md): Six steps from your manuscript to a finished EPUB and print PDF, and who does what.
- [Signing in and your books](https://studio.jdbb.net/help/sign-in.md): Your client code, the emailed sign-in link, and the page that lists your books.

## Your books

- [The transmittal](https://studio.jdbb.net/help/transmittal.md): The one-page form about your book. It sets the title pages, trim size, typography and copyright page.
- [Send your manuscript](https://studio.jdbb.net/help/send-your-manuscript.md): Upload one .docx from your editor. Heading 1 for chapters, named styles or [[markers]] for the rest.
- [Inspect](https://studio.jdbb.net/help/inspect.md): What the factory found in your file, how serious each finding is, and what to do next.
- [Build and download](https://studio.jdbb.net/help/build-and-download.md): Free proofs, counted finals, how long a build takes, and where your files are.
- [Your style sheet](https://studio.jdbb.net/help/style-sheet.md): Your book's editorial decisions (spelling, commas, capitals). Accept the studio's, edit them, or add your own.

## Inspect findings

- [Custom styles not in your transmittal](https://studio.jdbb.net/help/finding-undeclared-custom-style.md): Your file uses a paragraph or character style the transmittal doesn't list.
- [Book map: front / body / back matter](https://studio.jdbb.net/help/finding-book-map.md): How the build reads your file, and any warnings or notes about it.
- [Marked styles ([[style]] markers)](https://studio.jdbb.net/help/finding-style-marker.md): The [[markers]] Inspect found at the start of paragraphs, and what each becomes.
- [Headings without a Heading style](https://studio.jdbb.net/help/finding-heading-lookalike.md): A line that looks like a heading but is styled as body text, so the factory can't find it.
- [Spacing-sensitive or preformatted content](https://studio.jdbb.net/help/finding-special-typography.md): Text that looks like ASCII art or a preformatted block, where the spacing matters.
- [Stray \">\" marks from a pasted email](https://studio.jdbb.net/help/finding-stray-quote-marker.md): \">\" characters inside your running text, left over from a quoted email or Markdown.
- [Mixed fonts or sizes in one paragraph](https://studio.jdbb.net/help/finding-mixed-formatting.md): A paragraph with more than one font or size in it.

- [Non-Latin script](https://studio.jdbb.net/help/finding-language-script.md): Text in a non-Latin script, such as Greek, Cyrillic or Arabic.
- [Bold/italic applied by hand](https://studio.jdbb.net/help/finding-manual-formatting.md): Bold, italic or underline set directly on the text rather than by a style.
- [Lists typed by hand](https://studio.jdbb.net/help/finding-manual-list.md): Bullets or numbers typed as characters (-, *, 1.) instead of a list style.
- [Spacing/indent/alignment applied by hand](https://studio.jdbb.net/help/finding-direct-spacing.md): Spacing, indent or alignment set on a paragraph directly, not by a style.
- [Scene breaks done by hand](https://studio.jdbb.net/help/finding-manual-break.md): A scene break made with typed characters or a row of empty paragraphs.
- [Emoji or special font use](https://studio.jdbb.net/help/finding-font-treatment.md): Emoji or a special font in your text.
