Put the file in PM/files/, link to it from any doc, and rebuild. The build embeds it into the hub as a data URI, so PM/index.html stays a single offline file — the PDF travels inside it.

Add a PDF

# 1. drop the file in
cp ~/Downloads/spec-v2.pdf PM/files/

# 2. link to it from a doc (relative path from the .md to PM/files/)
#    in PM/docs/How-to/something.md:
#    [Spec v2](../../files/spec-v2.pdf)

# 3. rebuild
rocketman build

A PDF link renders as an attachment card with an Open / download button and an inline preview. Here is the sample shipped with Rocketman:

Add an image

Images embed inline. Use Markdown image syntax:

![Pipeline diagram](../../files/diagram.svg)

PNG, JPG, GIF, SVG, and WebP all work.

Rules & limits

Paths are relative to the .md file. From PM/docs/How-to/x.md, the files

folder is ../../files/.

Local only. http(s):// and data: links are left as-is, not embedded.
Size guard. Files over 8 MB are left as a plain link (not embedded) and the build

prints a warning, so the hub never balloons. Keep attachments small, or link out for big ones.

It stays offline. Because the bytes are embedded, the single PM/index.html opens

the PDF and shows the image with no network and no sidecar files.
