Should dbatools be installed on all SQL Servers

I'm looking to leverage dbatools powershell module for our SQL Server management needs. The install process does not lend itself for installation across a large number of servers. Is it really necessary or even a best practice to install dbatools across all SQL Servers in the environment or leverage a server we use for our database management as a central place to install to and manage from there? Seems like a lot of the commands I've looked at can be used remotely. Thank you.
