# Main Page

This is a preview for the new **MathML rendering mode** (with SVG fallback), which is availble in production for registered users.

If you would like use the **MathML** rendering mode, you need a wikipedia user account that can be registered here [[1]]

- Only registered users will be able to execute this rendering mode.
- Note: you need not enter a email address (nor any other private information). Please do not use a password that you use elsewhere.

Registered users will be able to choose between the following three rendering modes:

**MathML**

**Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "https://wikimedia.org/api/rest_v1/":): E=mc^{2}**

**PNG** (currently default in production)

**Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "https://wikimedia.org/api/rest_v1/":): E=mc^{2}**

**source**
