 \subsection{PMIx Roles}
 
 The role of a \ac{PMIx} process in the \ac{PMIx} universe is grouped into one of three categories based on how it operates in the \ac{PMIx} environment namely as a \emph{client}, \emph{server}, or \emph{tool}.
-As a result, there are three corresponding sets of initialization and finalization functions.
+As a result, there are three corresponding groupings of \acp{API} each with their own initialization and finalization functions.
 If a process initializes as either a \emph{server} or a \emph{tool} that process may also access all of the \emph{client} \acp{API}.
 
-A process operating as a \refterm{client} is started (directly or indirectly, for example, by an intermediate script) by the \ac{RM} and is connected to the \ac{PMIx} server instance within that \ac{RM} when the client calls the client \ac{PMIx} initialization routine.
+A process operating as a \refterm{client} is started directly or indirectly (for example, by an intermediate script) by the \ac{RM} and is connected to the \ac{PMIx} server instance within that \ac{RM} when the client calls the client \ac{PMIx} initialization routine.
 A process operating as a \declareterm{server} is responsible for starting client processes and coordinating with other server and tool processes in the same \ac{PMIx} universe.
 Often processes operating as a \emph{server} are part of the \acf{RM} infrastructure.
-A process operating as a \declareterm{tool} will connect to a \ac{PMIx} \emph{server} to interact with the processes in the \ac{PMIx} universe.
+A process operating as a \declareterm{tool} is started independently (e.g., via fork/exec) or by the \ac{RM} and will connect to a \ac{PMIx} \emph{server} to interact with the processes in the \ac{PMIx} universe.
 An example of a \emph{tool} process is a parallel debugger that will connect to the server to assist with attaching to a set of client processes.
 
 \ac{PMIx} serves as a conduit between processes acting in these three different roles.
