 # Inspection Lens <img align="right" src="logo.png" alt="Plugin Logo">
 
-Displays errors, warnings, and other inspections inline. Highlights the background of lines with inspections. Supports light and dark themes out of the box.
+IntelliJ plugin that shows errors, warnings, and other inspection highlights inline.
 
-By default, the plugin shows **Errors**, **Warnings**, **Weak Warnings**, **Server Problems**, **Grammar Errors**, **Typos**, and other inspections with a high enough severity level. Configure visible severities in **Settings | Tools | Inspection Lens**.
+After installing the plugin, inspection descriptions will appear after the ends of lines, and the lines will be highlighted with a background color. Shown inspection severities are **Errors**, **Warnings**, **Weak Warnings**, **Server Problems**, **Grammar Errors**, **Typos**, and other inspections from plugins or future IntelliJ versions that have a high enough severity level. Each severity has a different color, with support for both light and dark themes.
 
-Left-click an inspection to show quick fixes. Middle-click an inspection to navigate to the relevant code in the editor.
+Note: The plugin is not customizable outside the ability to disable/enable the plugin without restarting the IDE. If the defaults don't work for you, I recommend trying the [Inline Error](https://plugins.jetbrains.com/plugin/17302-inlineerror) plugin which can be customized, building your own version of Inspection Lens, or proposing your change in the [issue tracker](https://github.com/chylex/IntelliJ-Inspection-Lens/issues).
 
 Inspired by [Error Lens](https://marketplace.visualstudio.com/items?itemName=usernamehw.errorlens) for Visual Studio Code, and [Inline Error](https://plugins.jetbrains.com/plugin/17302-inlineerror) for IntelliJ Platform.

-    Left-click an inspection to show quick fixes. Middle-click an inspection to navigate to the relevant code in the editor. 
+    Note: The plugin is not customizable outside the ability to disable/enable the plugin without restarting the IDE.
