The PoshSec PowerShell module will include Updatable Help. So just like your other updatable help files, you can update PoshSec's helpfiles the same way.
Both PoshSec PowerShell Module and the PoshSec Framework will receive 2.0 updates before the end of the year in 2018. Keep an eye out on our Twitter account or on this site for more information as we release it.
To get started using the PoshSec PowerShell Module, take a look at our current PoshSec wiki for more information.
