 # Compile `javac` to a Wasm Module
 
-In this example, we'll compile the `javac` tool to Wasm modules that can then run on the commandline or the browser.
+This demo illustrates how to use the WebAssembly backend of GraalVM to compile the `javac` tool into a Wasm module that can then run on the command-line or in the browser.
