## Extra fonts

*Metro* and *Tiny Cursive* fonts are provided in **Display Modpack** (in **font_metro** and **boards** mods) but you can add more fonts by installing font mods. Be aware that each font mod comes with numerous textures. This can result in slowing media downloading and/or client display.

Extra font mods can be found here:
 * [OldWizard](https://github.com/pyrollo/font_oldwizard): An old style gothic font.
 * [Botic](https://github.com/pyrollo/font_botic): A scifi style font.
