+`muvm` allows you to run arbitrary programs from your system in a microVM. It's comprised of 2 small programs:
 
 - `muvm`: links against [libkrun](https://github.com/containers/libkrun) to create the microVM.
 
-- `muvm-guest`: acts as an entrypoint inside the microVM to set up the environment for running your program.
-
-- `muvm-server`: a server listening for requests to run additional programs. This allows you to run multiple graphical applications inside the same microVM.
+- `muvm-guest`: acts as an entrypoint inside the microVM to set up the environment for running your program. It spawns a server listening for requests to run additional programs. This allows you to run multiple graphical applications inside the same microVM.
