+MS SQL Extension for PHP 4.0 - Win32 README
+-------------------------------------------
+
+In order to compile this extension, copy sqlfront.h, sqldb.h and ntwdblib.lib to mssql-65 or mssql-70.
+These files are optaind from the MS SQL Server distribution CD
+
+You can change the file location by changing include and lib paths in the project.
