+
+By default, JetBrains Mono includes ligatures. The version without ligatures is called **JetBrains Mono NL** and can be found [here](https://github.com/JetBrains/JetBrainsMono/tree/master/fonts/ttf). This version is also stripped of all OpenType features, since they don't have any effect when your IDE doesn't support OpenType.
+
+If your IDE supports OpenType we recommend installing the default version of the font. If you prefer not using ligatures you can turn them off manually in the settings.
