 Semantic Highlighting
 ===============
-[Semantic Highlighting](https://github.com/redhat-developer/vscode-java/wiki/Semantic-Highlighting) is controlled by the `java.semanticHighlighting.enabled` preference. When enabled, it fixes numerous syntax highlighting issues with the default Java Textmate grammar. However, you might experience different small issues, particularly a delay when it kicks in, as it needs to be computed by the Java Language server, when opening a new file or when typing.
+[Semantic Highlighting](https://github.com/redhat-developer/vscode-java/wiki/Semantic-Highlighting) fixes numerous syntax highlighting issues with the default Java Textmate grammar. However, you might experience a few minor issues, particularly a delay when it kicks in, as it needs to be computed by the Java Language server, when opening a new file or when typing. Semantic highlighting can be disabled for all languages using the `editor.semanticHighlighting.enabled` setting, or for Java only using [language-specific editor settings](https://code.visualstudio.com/docs/getstarted/settings#_languagespecific-editor-settings).
