+A classloader framework for container developers who need more than Java's built-in hierarchy.
 
-Backward Compatibility
-----------------------
+Classworlds replaces the strict parent-child classloader tree with a pool of **realms** that can import
+specific packages from each other — a directed graph rather than a hierarchy. That is how Maven keeps a
+plugin's dependencies from colliding with its own, and how it loads plugins in isolation from one another.
+
+It also ships a [launcher](https://codehaus-plexus.github.io/plexus-classworlds/launcher.html) that builds
+the realms from a configuration file and invokes an application's `main` method in the right one. Maven's
+own startup scripts use it.
+
+## Status
+
+Maintained, conservatively. Maven's startup depends on this, so changes are deliberate and public API is
+kept compatible.
+
+## Using it
+
+```xml
+<dependency>
+  <groupId>org.codehaus.plexus</groupId>
+  <artifactId>plexus-classworlds</artifactId>
+  <version>2.12.0</version>
+</dependency>

+## Requirements
+
+Java 8 or later.
+
+## Backward Compatibility
 
 This project maintains a legacy compatibility layer in the `org.codehaus.classworlds` package.
 This package **cannot be removed** without coordinating with the Eclipse Sisu and Apache Maven teams.

 New code should use the `org.codehaus.plexus.classworlds` package.
