 ## Usage
 
 The procfs library is organized by packages based on whether the gathered data is coming from
-/proc, /sys, or both.  Each package contains an `FS` type which represents the path to either /proc, /sys, or both.  For example, current cpu statistics are gathered from

+## Package Organization
+
+The packages in this project are organized according to (1) whether the data comes from the `/proc` or
+`/sys` filesystem and (2) the type of information being retrieved.  For example, most process information
+can be gathered from the functions in the root `procfs` package.  Information about block devices such as disk drives
+is available in the `blockdevices` sub-package.

 ## Building and Testing
 
-The procfs library is normally built as part of another application.  However, when making
-changes to the library, the `make test` command can be used to run the API test suite.
+The procfs library is intended to be built as part of another application, so there are no distributable binaries.
