 ## Overview
 
 A lightweight extension to provide additional Java project explorer features. It works with [Language Support for Java by Red Hat](https://marketplace.visualstudio.com/items?itemName=redhat.java) to provide the following features:

+
+### Manage Dependencies
+
+You can work with JAR files directly without any build tools. Go to `JAVA PROJECTS` view, find the `Referenced Libraries` node and click the `+` icon:
+
+![Reference JAR Files](https://raw.githubusercontent.com/Microsoft/vscode-java-dependency/main/images/manage-dependencies.gif)
+
+If you want to fine-tune this, go to `settings.json` and look for the `java.project.referencedLibraries` entry.
+
+```json
+"java.project.referencedLibraries": [
+    "library/**/*.jar",
+    "/home/username/lib/foo.jar"
+]
+```
+
+You can tell that the glob pattern is supported. And here's more - you can  include/exclude certain files, and attach source JARs:
+
+```json
+"java.project.referencedLibraries": {
+    "include": [
+        "library/**/*.jar",
+        "/home/username/lib/foo.jar"
+    ],
+    "exclude": [
+        "library/sources/**"
+    ],
+    "sources": {
+        "library/bar.jar": "library/sources/bar-src.jar"
+    }
+}
+```
