I. Introduction
----------------------------------------------------------------------------
Perfkit is a performance recording toolkit for developers and system
administrators. It can be used for both profiling systems software and
applications as well as monitoring servers and remote devices.
----------------------------------------------------------------------------
II. Installation
----------------------------------------------------------------------------
Perfkit is packaged in the standard format for most GNU/Linux-based software.
Use the standard `./configure', `make', `make install' to build and install
Perfkit.
Perfkit contains a runtime agent that manages profiling and systems
monitoring. It can be run using `perfkit-agent'.
In the near future, a GUI will be provided to manage Perfkit recording
sessions.
----------------------------------------------------------------------------
III.	Contributing
----------------------------------------------------------------------------
Perfkit is actively looking for contributors to help improve the codebase
and add collection data sources.
You can find more information on the architecture of Perfkit and a layout
of the codebase in HACKING which can be found in the same directory as this
file.
