+Using Fonts
+===========
+
+Godot allows you to set specific fonts for different UI nodes.
+
+There are 3 places you can setup font usage. The first is the
+theme editor. choose the node you want to set the font for
+and select the font tab. The second is in the inspector for
+control nodes under **Theme Overrides > Fonts**. And lastly in
+the inspector settings for themes under **Default Font**
+
+Regardless of where you are creating the font the process is
+the same. Click on the font setting you want to add a font to
+and a dropdown will appear with two choices **New Bitmap Font**
+and **New Dynamic Font**.
+
+.. image:: img/new_font.png
+
+If you have a bitmap font file (.fnt) do not select New Bitmap
+Font. Instead, drag the file from the file system panel to the
+font slot. Selecting the font after adding it to the font slot
+gives you 3 settings that can be changed. Height, ascent and
+Distance Field. Distance field fonts were never reimplemented
+for Godot 3.0 and do not work.
+
+If you are using a true type font file (.ttf) select **New Dynamic
+Font**. From here select **Font** and drag your .ttf file to the
+Font Data slot. The dynamic font resource is now using the font
+you selected.
+
+There are several options you can adjust. **Extra Spacing** options
+control the spacing of characters. **Settings** control the general
+settings of the font.
+
+.. image:: img/dynamic_font_options.png
+
+If you want to use the same font again but with different settings,
+such as a larger size or an outline, create another dynamic font
+resource, add the same .ttf file, and make the adjustments that you
+want.
