+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 --buildtype=release -D with-contrib=true -D with-tests=true -D with-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).

-This Meson project 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 (`zstd/contrib/meson`) and type:
-
-```sh
-meson --buildtype=release --strip --prefix=/usr 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 the build, use:
-
-```sh
-meson configure
-```
-
-See [man meson(1)](https://manpages.debian.org/testing/meson/meson.1.en.html).
