 ## Overview
 
-FlowIO is a Python library for reading / writing Flow Cytometry Standard (FCS)
-files, with minimal dependencies and is compatible with Python 3.9+.
-
-For higher level interaction with flow cytometry data, including GatingML and FlowJo 10 support, 
-see the related [FlowKit](https://github.com/whitews/FlowKit) project.
+FlowIO is a Python library for reading and writing Flow Cytometry Standard (FCS)
+files, with minimal dependencies and is compatible with Python 3.9+. It is intended 
+as a lightweight library, suitable for parsing FCS data sets (e.g. as a web server 
+backend, for simple metadata extraction, etc.). It is **highly recommended** that 
+one be familiar with the various FCS file standards (2.0, 3.0, 3,1) before using 
+FlowIO for downstream analysis. For higher level cytometry analysis, please see the 
+related [FlowKit](https://github.com/whitews/FlowKit) library which offers a much 
+wider set of analysis options such as compensation, transformation, and gating 
+support (including support for importing FlowJo 10 workspaces).
+
+If you have any questions about FlowIO, find any bugs, or feel something is missing 
+from the documentation [please submit an issue to the GitHub repository here](https://github.com/whitews/FlowIO/issues/new/).
