-Very preliminary version
+You need gcc version 2.0 or later to compile gforth.
 
-Create a machine description file for your machine, if necessary.
+First, type
 
-Make a symbolic link to machine.h, e.g.
+./configure
 
-ln -s decstation.h machine.h
+configure has the following useful parameters:
+  --prefix=PREFIX         install architecture-independent files in PREFIX
+                          [default: /usr/local]
+  --exec-prefix=PREFIX    install architecture-dependent files in PREFIX
+                          [default: same as prefix]
+  --enable-force-reg      Use explicit register declarations if they appear in
+                          the machine.h file. This can cause a good speedup,
+                          but also incorrect code with some gcc versions on
+                          some processors (default disabled).
+  --enable-direct-threaded      Force direct threading. This may not work on
+                                some machines and may cause slowdown on others.
+                                (default processor-dependent)
+  --enable-indirect-threaded    Force indirect threading. This can cause a
+                                slowdown on some machines.
+                                (default processor-dependent)
+  --with-debug     specifies option -g to compile with debug info (default)
+   --without-debug  omits the -g switch and creates smaller images on
+                    machines where strip has problems with gcc style
+                    debugging informations.
+  --help: tells you about other parameters.
 
-Now you can type
+If you don't like the defaults for the installation directories, you
+should override them already during configure.  E.g., if you want to
+install in the /gnu hierarchy instead of in the default /usr/local
+hirarchy, say
+
+./configure --prefix=/gnu
+
+After, configuration, type
 
 make
+
+If your make has trouble with the Makefile, "make gforth" might work.
+
+If your installed gcc isn't called "gcc" (e.g., called "gcc-2.6.1"), type
+
+make GCC=<whatever you call your gcc>
+
+instead.
+
+Now you can check whether your shiny new Forth system works. Say
+
+make test
+
+To make the documentation, type
+
+make -k gforth.info gforth.ps html
+
+If everything is allright, you may want to install gforth. Type
+
+make install
+
+You have to make an entry in the info directory file manually. Also,
+you have to install gforth.ps and html yourself.
