+the EDK2BASE variable in the filesystems/Make.common file in the rEFInd
+source package. You can then type "make" in the "filesystems" directory,
+or "make fs" in the main source directory, to build all the drivers. If you
+want to build just one driver, you can change into the "filesystems"
+directory and type "make {fsname}", where {fsname} is a filesystem name --
+"ext2", "reiserfs", "iso9660", or "hfs". The drivers will appear in the
+"filesystems" directory, and also be copied to the "drivers" directory.
+
+To install drivers, you can type "make install" in the "filesystems"
+directory. This copies all the drivers to the
+"/boot/efi/EFI/refind/drivers" directory. Alternatively, you can copy the
+files you want manually.
+
+*CAUTION:* Install drivers for your system's architecture *ONLY*.
+Installing drivers for the wrong architecture causes some systems to hang
+at boot time.
