 # Inspection Lens <img align="right" src="logo.png" alt="Plugin Logo">
 
-IntelliJ plugin that shows errors, warnings, and other inspection highlights inline.
+Displays errors, warnings, and other inspections inline. Highlights the background of lines with inspections. Supports light and dark themes out of the box.
 
-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.
+By default, the plugin shows **Errors**, **Warnings**, **Weak Warnings**, **Server Problems**, **Grammar Errors**, **Typos**, and other inspections with a high enough severity level. 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).
+Configure appearance, behavior of clicking on inspections, and visible severities in **Settings | Tools | Inspection Lens**.
 
 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.

-    Shows errors, warnings, and other inspection highlights inline.
+    Displays errors, warnings, and other inspections inline. Highlights the background of lines with inspections. Supports light and dark themes out of the box.
     <br><br>
-    After installing the plugin, inspection descriptions will appear after the ends of lines, and the lines will be highlighted with a background color.
+    By default, the plugin shows <b>Errors</b>, <b>Warnings</b>, <b>Weak Warnings</b>, <b>Server Problems</b>, <b>Grammar Errors</b>, <b>Typos</b>, and other inspections with a high enough severity level. Left-click an inspection to show quick fixes. Middle-click an inspection to navigate to the relevant code in the editor.
-    Shown inspection severities are <b>Errors</b>, <b>Warnings</b>, <b>Weak Warnings</b>, <b>Server Problems</b>, <b>Grammar Errors</b>, <b>Typos</b>, 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.
     <br><br>
-    Note: The plugin is not customizable outside the ability to disable/enable the plugin without restarting the IDE.
+    Configure appearance, behavior of clicking on inspections, and visible severities in <b>Settings | Tools | Inspection Lens</b>.
-    If the defaults don't work for you, I recommend trying the <a href="https://plugins.jetbrains.com/plugin/17302-inlineerror">Inline Error</a> plugin which can be customized, building your own version of Inspection Lens, or proposing your change in the <a href="https://github.com/chylex/IntelliJ-Inspection-Lens/issues">issue tracker</a>.
     <br><br>
     Inspired by <a href="https://marketplace.visualstudio.com/items?itemName=usernamehw.errorlens">Error Lens</a> for VS Code, and <a href="https://plugins.jetbrains.com/plugin/17302-inlineerror">Inline Error</a> for IntelliJ Platform.
