+The aim of this package is to make reading the INSTALL file unnecessary. So
+next time try running:
+
+$ bpkg build libcmark-gfm-extensions
+
+But if you don't want to use the package manager, then you can also build this
+package manually using the standard build2 build system.

+cmark-gfm is an extended version of cmark, the reference implementation of
+CommonMark parsing and rendering C library. In addition to libcmark,
+libcmark-gfm provides extensions management support. The GitHub Flavored
+Markdown extensions themselves are provided by libcmark-gfm-extensions.
+
+https://github.com/github/cmark-gfm
+
+This package contains the original libcmark-gfm-extensions library source code
+overlaid with the build2-based build system and packaged for the build2
+package manager (bpkg).
+
+See the INSTALL file for the prerequisites and installation instructions.
+
+Post questions, bug reports, or any other feedback about the library itself at
+https://github.com/github/cmark-gfm/issues. Send build system and
+packaging-related feedback to the packaging@build2.org mailing list (see
+https://lists.build2.org for posting guidelines, etc).
+
+The packaging of libcmark-gfm for build2 is tracked in a Git repository at:
+
+https://git.build2.org/cgit/packaging/cmark-gfm/

+This document describes how libcmark-gfm-extensions was packaged for build2.
+In particular, this understanding will be useful when upgrading to a new
+upstream version. See ../README-DEV for general notes on cmark-gfm packaging.
+
+Symlink the required upstream files and directories into
+libcmark-gfm-extensions/:
+
+$ ln -s ../../upstream/extensions libcmark-gfm-extensions
+
+Create cmark-gfm-extensions_export.h defining CMARK_GFM_EXTENSIONS_EXPORT
