 ## Installation:
 
+The following instructions install the library and header files in the standard
+system locations. If you want to install it in a different location, you can pass
+extra arguments to the configure script.
+
+In particular, if you want to install it so it can be used from a SageMath install
+you have to use
+
+```
+./configure --prefix=<sagedir>/local --libdir=<sagedir>/local/lib
+```
+where <sagedir> is the directory where SageMath is installed.
