Upload the pdf first. Note: you cannot upload large files. For large files, write the text out manually.

To display a particular page, use: [[File:UPLOAD_NAME.pdf|page=1|600px]]. You can set the page number via page=N and here we've set the size to 600 pixels.

## Images

Upload the image first. Note: you cannot upload very large files. Try reducing the image size or upload to a special image storage website like Imgur and link to that page.

For examples, go to mw:Help:Images.

## Tables

See mw:Help:Tables and w:Help:Table.
