-IntelliJ plugin that shows errors, warnings, and other inspection highlights inline.
+# Inspection Lens <img align="right" src="logo.png" alt="Plugin Logo">
 
-Simply install the plugin and inspection descriptions will appear on the right side of the lines. Shown inspection severities are **Errors**, **Warnings**, **Weak Warnings**, **Server Problems**, **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.
+Displays errors, warnings, and other inspections inline. Highlights the background of lines with inspections. Supports light and dark themes out of the box.
 
-The plugin is not customizable outside of the ability to disable/enable the plugin without restarting the IDE. If the defaults don't work for you, I would recommend either trying the [Inline Error](https://plugins.jetbrains.com/plugin/17302-inlineerror) plugin which can be customized, or proposing your change in the [issue tracker](https://github.com/chylex/IntelliJ-Inspection-Lens/issues).
+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.
+
+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.

-##  Gradle start up script for UN*X
-##
+#
+#   Gradle start up script for POSIX generated by Gradle.
+#
+#   Important for running:
+#
+#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
+#       noncompliant, but you have some other compliant shell such as ksh or
+#       bash, then to run this script, type that shell name before the whole
+#       command line, like:
+#
+#           ksh Gradle
+#
+#       Busybox and similar reduced shells will NOT work, because this script
+#       requires all of these POSIX shell features:
+#         * functions;
+#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
+#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
+#         * compound commands having a testable exit status, especially «case»;
+#         * various built-in commands including «command», «set», and «ulimit».
+#
+#   Important for patching:
+#
+#   (2) This script targets any POSIX shell, so it avoids extensions provided
+#       by Bash, Ksh, etc; in particular arrays are avoided.
+#
+#       The "traditional" practice of packing multiple parameters into a
+#       space-separated string is a well documented source of bugs and security
+#       problems, so this is (mostly) avoided, by progressively accumulating
+#       options in "$@", and eventually passing that to Java.
+#
+#       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
+#       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
+#       see the in-line comments for details.
+#
+#       There are tweaks for specific operating systems such as AIX, CygWin,
+#       Darwin, MinGW, and NonStop.
+#
+#   (3) This script is generated from the Groovy template
+#       https://github.com/gradle/gradle/blob/HEAD/platforms/jvm/plugins-application/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
+#       within the Gradle project.

   <description><![CDATA[
-    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>
-    Simply install the plugin and inspection descriptions will appear on the right side of the lines.
-    Shown inspection severities are <b>Errors</b>, <b>Warnings</b>, <b>Weak Warnings</b>, <b>Server Problems</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.
+    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.
     <br><br>
-    The plugin is not customizable outside of the ability to disable/enable the plugin without restarting the IDE.
-    If the defaults don't work for you, I would recommend either trying the <a href="https://plugins.jetbrains.com/plugin/17302-inlineerror">Inline Error</a> plugin which can be customized, or proposing your change in the <a href="https://github.com/chylex/IntelliJ-Inspection-Lens/issues">issue tracker</a>.
+    Configure appearance, behavior of clicking on inspections, and visible severities in <b>Settings | Tools | Inspection Lens</b>.
     <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.
