 This is a project for tracking test coverage in PL/PgSQL functions.  Very much
 a work in progress, so things will probably break and/or won't work correctly.
 
+To run, you need to add "pgcov" to shared\_preload\_libraries.  To build on
+9.1, you need to do an in-tree build NO\_PGXS=1.
+
 Requires PostgreSQL 9.1 or newer.
