 ### Prerequisites
 
-This package requires the [NCEPLIBS-sp](https://github.com/NOAA-EMC/NCEPLIBS-sp) library.
+This package does not link to any other libraries, but requires CMake (version
+3.15+) to build.
 
 ### Installing
 
 ```
 mkdir build
 cd build
-cmake -DCMAKE_INSTALL_PREFIX=/path/to/install /path/to/NCEPLIBS-ip2
+cmake -DCMAKE_INSTALL_PREFIX=/path/to/install /path/to/NCEPLIBS-ip
 make -j2
-make test (or ctest --verbose)
+make test # (or ctest --verbose)
 make install
 ```
 
 ### Usage
 
-To use the ip library add `use ip_mod` to your Fortran code. It contains all the necessary public interfaces.
+Most routines and any public interfaces required can be accessed by adding `use
+ip_mod` to your Fortran code. Most spectral transform and processing subroutines
+can be accessed by calling them in your code (no `use` statement) and linking
+to the ip library at build time.
