-Creating database skeleton tables
-===================================
+Creating functions
+====================
+
+Run this command in the db/functions directory:
+
+$ make
+
+The above command should work for linux and most other Unix systems
+that use ELF shared objects. For MacOS X you will need to do:
+
+$ make libquadtile.dylib
+
+Make sure the db/functions directory is on the MySQL server's library
+path and restart the MySQL server. On linux the easiest way to do this
+is to create /etc/ld.so.conf.d/osm.conf and place the path to the
+db/functions directory in it and then run the following command as root:
+
+$ ldconfig
+
+Now create the functions as follows:
 
-$ mysql openstreetmap -u openstreetmap -p < db/create_database.sql
+$ mysql -u <uid> -p openstreetmap
 
-New server patch (RAILS)
-==========================
+(change <uid> with appropriate username of administrative user eg. root )
+
+> create function tile_for_point returns integer soname 'libquadtile.so';
+> exit
+
+or, for MacOS X:
+
+> create function tile_for_point returns integer soname 'libquadtile.dylib';
+> exit
+
+Creating database skeleton tables

+$ rake db:migrate
 
+This will create the db for you
