# Is the Siunitx LaTeX package supported?


### Siunitx LaTeX package
 
From the toolbar, click on Settings ⚙  and select Edit Macros. This will open a file called header.tex for editing. This is the file where all packages and macros are defined. Add this line:

`\usepackage{siunitx}`
Then go back to the Document view and type in a LaTeX block SI units, such as `\si{\meter}` which will render as _m_.
