 To install dependencies on Fedora:
 
-    sudo dnf install freetype-devel harfbuzz-devel fribidi-devel gtk-doc
+    sudo dnf install freetype-devel harfbuzz-devel fribidi-devel meson gtk-doc
 
 To install dependencies on Ubuntu:

 On Mac OS X you can use Homebrew:
 
-    brew install freetype harfbuzz fribidi gtk-doc
+    brew install freetype harfbuzz fribidi meson gtk-doc
     export XML_CATALOG_FILES="/usr/local/etc/xml/catalog" # for the docs
 
 Once you have the source code and the dependencies, you can proceed to build.
 To do that, run the customary sequence of commands in the source code
 directory:
 
-    $ ./configure
-    $ make
-    $ make install
+    $ meson build
+    $ ninja -C build
+    $ ninja -C build install
 
-To build the documentation, pass `--enable-gtk-doc` to the `configure` script.
+To build the documentation, pass `-Ddocs=enable` to the `meson`.
 
 To run the tests:
 
-    $ make check
+    $ ninja -C test
