+# Plugin for IntelliJ IDEA
+
+[//]: # (excludeFromIndex)
+
+We introduce the alpha version of the plugin for IntelliJ IDEA 2024.3.x+ IDE variants. It is compatible with 2025.x and
+should be compatible with other IDEA flavors, notably [OpenIDE](https://openide.ru/). It supports the following features:
+
+- syntax highlighting (2 stage, fast and more accurate that analyses in background)
+- reformat code (indents, spaces)
+- reformat on paste
+- smart enter key
+
+Features are configurable via the plugin settings page, in system settings.
+
+> Recommended for IntelliJ-based IDEs: While IntelliJ can import TextMate bundles
+> (Settings/Preferences → Editor → TextMate Bundles), the native Lyng plugin provides
+> better support (formatting, smart enter, background analysis, etc.). Prefer installing
+> this plugin over using a TextMate bundle.
+
+### Install
+
+- From ZIP: download the archive below, then in IntelliJ IDEA open Settings/Preferences → Plugins →
+  gear icon → Install Plugin from Disk… and select the downloaded ZIP. Restart IDE if prompted.
+- Alternatively, if/when the plugin is published to a marketplace, you will be able to install it
+  directly from the “Marketplace” tab (not yet available).
