# Building jMonkeyEngine 3 from the Sources

We recommend downloading the
- but of course you can also build the jMonkeyEngine yourself from the sources. In this case, you need the
file version system installed (svn).

1. Checkout: Checkout the Subversion repository.

       svn checkout http://jmonkeyengine.googlecode.com/svn/trunk/engine jme3

   - You can leave login and password empty
2. Build: Execute `ant jar`
   - This compiles the JAR files in `dist/libs/*`
3. Javadoc: Execute `ant javadoc`
   - This generates javadocs in the `dist/javadoc` directory.
4. Run: Execute `ant run`
   - This runs the TestChooser where you can browse examples.
5. Use: Create a Java SE project and place all JARs from the `dist/lib` directory on the classpath.
   - You can now extend your first game from `com.jme3.app.SimpleApplication`.

For a detailed description of the created jar files see this list.
