+<html>
+<body>
+Write your description here.
+Start the description with a verb in 3rd person singular, like reports, detects, highlights.
+In the first sentence, briefly explain what exactly the inspection helps you detect.
+Make sure the sentence is not very long and complicated.
+<p>
+The first sentence must be in a dedicated paragraph separated from the rest of the text. This will make the description easier to read.
+Make sure the description doesn’t just repeat the inspection title.
+</p>

+See https://jetbrains.design/intellij/text/inspections/#descriptions for more information.

+</code></pre>
+<!-- tooltip end -->
+<p>Text after this comment will only be shown in the settings of the inspection.</p>
