+Glyphs
+------
+
+A style's ``glyphs`` property provides a URL template for loading
+signed-distance-field glyph sets in PBF format.
+
+::
+
+    "glyphs": "{fontstack}/{range}.pbf"
+
+
+This URL template should include two tokens:
+
+-  ``{fontstack}`` When requesting glyphs, this token is replaced with a
+   comma separated list of fonts from a font stack specified in the
+   ```text-font`` <#layout-symbol-text-font>`__ property of a symbol
+   layer.
+-  ``{range}`` When requesting glyphs, this token is replaced with a
+   range of 256 Unicode code points. For example, to load glyphs for the
+   `Unicode Basic Latin and Basic Latin-1 Supplement
+   blocks <https://en.wikipedia.org/wiki/Unicode_block>`__, the range
+   would be ``0-255``. The actual ranges that are loaded are determined
+   at runtime based on what text needs to be displayed.
