                ELKS, the Embeddable Linux Kernel Subset
                ----------------------------------------
 
-This is a project to write a Linux-like operating system for ancient
-computers running an Intel 8086-compatible processor.
+This is a project to write a Linux-like operating system for systems based on
+the Intel IA16 architecture (16 bits processors: i8088, i8086, i80188, i80186,
+i80286, V20, V30 and compatibles).
 
-To build ELKS, you will need a cross build chain, mainly based on DEV86, and
-also on GCC-IA16 if you select that latest in place of BCC to build the kernel.
+Such systems are ancient computers (IBM-PC XT/AT and clones) or more recent
+embedded ones that reuse their huge hardware & software legacy.

+To build ELKS, you need a cross build chain, mainly based on DEV86 (still used
+for the user land) and GCC-IA16 (now used for the kernel).
 
 A script is provided to automatically download and build that cross chain:
 
   'tools/build.sh'
 
-Note: all the scripts must be executed with top folder 'elks/' as the current one.

 The target root folder is built in 'target/', and depending on your
 configuration, that folder is packed as either a floppy disk image (fd1440,
 fd1680, fd1200, fd720, fd360, without MBR), a hard-disk image (hd, with MBR),
 or a file image (rom, tar), into the '/image' folder.
