 # aWsm (awesome)
 
-**aWsm** is an efficient WASM runtime built with the `silverfish` compiler. This is an active research effort with regular breaking changes and no guarantees of stability.
+**aWsm** is an efficient serverless runtime built with the `silverfish` compiler. It combines WebAssembly sandboxing with asynchronous I/O to provide a lightweight serverless solution suitable for edge computing.
 
 ## Host Dependencies

-Additionally, if you want to execute the Awsm runtime on your host environment, you need libuv. A reason you might want to do this is to debug your serverless function, as GDB does not seem to run properly within a Docker container.
