+Meson build system for zstandard
+================================
+
+Meson is a build system designed to optimize programmer productivity.
+It aims to do this by providing simple, out-of-the-box support for
+modern software development tools and practices, such as unit tests,
+coverage reports, Valgrind, CCache and the like.
+
+This Meson build system is provided with no guarantee and maintained
+by Dima Krasner \<dima@dimakrasner.com\>.
+
+It outputs one `libzstd`, either shared or static, depending on
+`default_library` option.
+
+## How to build
+
+`cd` to this meson directory (`build/meson`)
+
+```sh
+meson setup -Dbin_programs=true -Dbin_contrib=true builddir
+cd builddir
+ninja             # to build
+ninja install     # to install
+```
+
+You might want to install it in staging directory:
+
+```sh
+DESTDIR=./staging ninja install
+```
+
+To configure build options, use:
+
+```sh
+meson configure
+```
+
+See [man meson(1)](https://manpages.debian.org/testing/meson/meson.1.en.html).
