+Building
+--------
+
+This project is built with meson. See the manual for detailed usages:
+https://mesonbuild.com/Running-Meson.html
+
+In short, from the source directory, you can configure, build and test the
+project with those commands:
+$ meson builddir
+$ ninja -C builddir
+$ ninja -C builddir test
+
+For convenience, a Makefile wraps meson for you with the regular "make", "make
+check" and "make install" targets. Although further build tweaking will require
+you to invoke meson manually.
