+Using Fonts
+===========
+
+Godot allows you to set specific fonts for different UI nodes.
+
+There are three different places where 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
+
+Bitmap fonts (``.fnt``) are a format created by `BMFont <http://www.angelcode.com/products/bmfont/>`__
+(many BMFont compatible programs exist, like `BMGlyph <http://www.bmglyph.com/>`__).
+If you are using a ``.fnt`` file 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 three settings that can be changed: **height**, **ascent**
+and **distance field**. Distance field fonts were never reimplemented
+for Godot 3 and do not work in that version.
+
+Dynamic Font supports the following formats:
+- TrueType (``.ttf``)
+- OpenType (``.otf``)
+- Web Open Font Format 1 (``.woff``)
+
+If you are using one of these select **New Dynamic Font**.
+Click on it to open its settings in the inspector. From here
+open the **Font** settings and add your font 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
+
+In addition, the font data has antialiasing and hinting settings you
+can see if you click on it. If you want to adjust either of these
+you need to make the font data resource unique, then save it to a
+``.tres`` file. Adjusting the font file will not work because ``.ttf``/
+``.otf``/ ``.woff`` files can't contain metadata about antialiasing
+or hinting.
+
+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 using the same font file, and make the adjustments that you
+want.
