Autocomplete showing methodinformation

Hello everyone

I have a general question concerning autocomplete. I am using Atom with PlatformIo and enjoying the overall functionality programming on microcontroller.
I am generally using Netbeans and now I used to the autocomplete function, which also shows basic information about the variables and functions.


Autocomplete is working fine in Atom (PIO) but only shows the available functions and return types.

Is there a package which can include metainformation from the documentation (like javadoc)?
