 The WAMR samples are located in folder [./samples](./samples). A sample usually contains the WAMR runtime build, WASM applications and test tools. The WARM provides following samples:
-- [Simple](./samples/simple/README.md): The runtime integrated most of the WAMR APP libaries and multiple WASM applications are provided for using different WASM API set.
-- [littlevgl](./samples/littlevgl/README.md): Demostrating the graphic user interface application usage on WAMR. The whole littlevgl 2D user graphic library and the UI application is built into WASM application.  
-- [gui](./samples/gui/README.md): Moved the littlevgl library into the runtime and defined a WASM application interface by wrapping the littlevgl API.
