 ## Using the libraries
 As the types are entirely implemented inline in headers, there are no linking requirements.
 
-Just place the contents of the [include](./include) directory within your source tree so it is available
-to your compiler, then include the appropriate headers in your program, and away you go!
+You can copy the [gsl](./gsl) directory into your source tree so it is available
+to your compiler, then include the appropriate headers in your program.
+
+Alternatively set your compiler's *include path* flag to point to the GSL development folder (`c:\GSL` in the example above) or installation folder (after running the install). Eg.
