+This information supplements the generic installation instructions in
+the file 'INSTALL'.  It is meant for people building from the
+development repository, rather than a distribution archive.
+Distribution archives include a 'configure' script, among other files;
+the repository does not.  If you want to start building the 'groff'
+system using an existing 'configure' script, you don't need the
+information in this file.
+
+Dependencies
+------------
+
+The dependencies documented in the 'INSTALL.extra' file are required, as
+are several others.
+
+* You will need Autoconf version 2.68 or higher and Automake version
+  1.12.2 or higher.  These requirements are asserted in the
+  'bootstrap.conf' file.
+
+  On operating systems supporting concurrent installation of multiple
+  versions of the GNU Autotools, set environment variables as in the
+  following example, adjusting the version numbers as required.
+
+    $ export AUTOMAKE_VERSION=1.14
+    $ export AUTOCONF_VERSION=2.69
+
+* You will need a 'yacc' program.  We recommend Berkeley yacc ('byacc')
+  or GNU Bison ('bison').
+
+* groff's Texinfo manual is generated in several formats: GNU Info,
+  HTML, plain text, TeX DVI, and PDF.  The former three require
+  'makeinfo' from GNU Texinfo 5.0 or later.  The latter two additionally
+  require a TeX installation, such as TeX Live.  If TeX is not
+  installed, the DVI and PDF formats of the manual cannot be generated.
+  This will cause a build failure only if the Texinfo source file
+  "groff.texi" is updated and the make(1) "dist" or relevant file
+  targets are manually specified.
+
+* You will need the 'xpmtoppm', 'pnmdepth', and 'pnmtops' programs from
+  the Netpbm distribution.
+
+
+Bootstrapping from a Git checkout
+---------------------------------
+
+Invoke the bootstrap script.
+
+    $ ./bootstrap
+
+
+What bootstrapping does
+-----------------------
+
+The foregoing procedure will do two things:
+
+  - clone the gnulib repository as a Git submodule in 'gnulib', add the
+    needed gnulib source files in 'lib' as well as required gnulib m4
+    macros in 'gnulib_m4'; and
+
+  - invoke 'autoreconf', which will call the GNU Autotools ('aclocal',
+    'autoconf', 'automake') in the right order to create the following
+    files.
+
+    -- INSTALL (a symlink to gnulib's INSTALL file)
+    -- Makefile.in
+    -- aclocal.m4
+    -- autom4te.cache/
+    -- build-aux/ (which contains all the helper scripts)
+    -- configure
+    -- src/include/config.hin
+
+'aclocal.m4' is a generated file; groff's m4 macros are included via the
+'acinclude.m4' file.
+
+
+Building
+--------
+
+You can now invoke the 'configure' script.  It produces the
+'config.status' script, which generates the Makefile.  Then call 'make'
+to build the groff project.  You can do these from the source tree.
+
+    $ ./configure
+    $ make # run with -j option if desired
+
+You can alternatively build groff outside of its source tree, which is
+cleaner, leaving fewer files to confuse 'git status' if you aim to
+undertake development.
+
+    $ mkdir build
+    $ cd build
+    $ ../configure
+    $ make # run with -j option if desired
+
+A separate build tree need not be a subdirectory of the source.
+
+
+Evaluation
+----------
+
+Several dozen sanity checks can be performed within the build tree.
+
+    $ make check # run with -j option if desired
+
+
+Installation
+------------
+
+When the build is finished you can install the groff build artifacts.
+
+    $ make install install-doc # run with 'sudo' if necessary
+
+
+Uninstalling
+------------
+
+See "Uninstalling" in the 'INSTALL.extra' file.
+
+
+Rebuilding
+----------
+
+Start over from "Building" above.
