 ## Build and run VisualVM plugins
 
 To build or run the plugins suite, use `ant build` or `ant run` in the `visualvm/plugins` directory. This will automatically build the zip distribution of the core VisualVM tool into `visualvm/visualvm/dist/visualvm.zip` and extract it into the `visualvm/plugins/visualvm` directory. After that the build of the plugins suite continues to build each of the individual plugins. Running the plugins suite means starting VisualVM with all the plugins installed.
