 Once you have all the necessary dependencies, you can build GTK by using
 Meson:
 
 ```sh
-$ meson _build .
-$ cd _build
-$ ninja
+$ meson setup _build
+$ meson compile -C_build
 ```
 
 You can run the test suite using:
 
 ```sh
-$ meson test
+$ meson test -C_build
 ```
 
 And, finally, you can install GTK using:
 
 ```
-$ sudo ninja install
+$ sudo meson install -C_build
 ```

+--------

+|
+|   **gtk4-path-tool** decompose [OPTIONS...] <PATH>
+|   **gtk4-path-tool** show [OPTIONS...] <PATH>

+|   **gtk4-path-tool** info [OPTIONS...] <PATH>
+
+DESCRIPTION
+-----------
+
+``gtk4-path-tool`` can perform various tasks on paths. Paths are specified
+in SVG syntax, as strings like "M 100 100 C 100 200 200 200 200 100 Z".
+
+To read a path from a file, use a filename that starts with a '.' or a '/'.
+To read a path from stdin, use '-'.
+
+COMMANDS
+--------
+
+Decomposing
+^^^^^^^^^^^
+
+The ``decompose`` command approximates the path by one with simpler elements.
+When used without options, the curves of the path are approximated by line
+segments.
+
+``--allow-quad``
+
+  Allow quadratic Bézier curves to be used in the generated path.
+
+``--allow-cubic``
+
+  Allow cubic Bézier curves to be used in the generated path.
+
+Showing
+^^^^^^^
+
+The ``show`` command displays the given path in a window. The interior
+of the path is filled.
+
+``--fill-rule=VALUE``
+
+  The fill rule that is used to determine what areas are inside the path.
+  The possible values are ``winding`` or ``even-odd``. The default is ``winding``.
+
+``--fg-color=COLOR``
+
+  The color that is used to fill the interior of the path or stroke the path.
+  If not specified, black is used.
+
+``--bg-color=COLOR``
+
+  The color that is used to render the background behind the path.
+  If not specified, white is used.
+
+``--stroke``
+
+  Stroke the path instead of filling it.
+
+``--line-width=VALUE``
+
+  The line width to use for the stroke. ``VALUE`` must be a positive number.
+  The default line width is 1.
+
+``--line-cap=VALUE``
+
+  The cap style to use at line ends. The possible values are ``butt``, ``round``
+  or ``square``. See the SVG specification for details on these styles.
+  The default cap style is ``butt``.
+
+``--line-join=VALUE``
+
+  The join style to use at line joins. The possible values are ``miter``,
+  ``miter-clip``, ``round``, ``bevel`` or ``arcs``. See the SVG specification
+  for details on these styles.
+  The default join style is ``miter``.
+
+``--miter-limit=VALUE``
+
+  The limit at which to clip miters at line joins. The default value is 4.
+
+``--dashes=VALUE``
+
+  The dash pattern to use for this stroke. A dash pattern is specified by
+  a comma-separated list of alternating non-negative numbers. Each number
+  provides the length of alternate "on" and "off" portions of the stroke.
+  If the dash pattern is empty, dashing is disabled, which is the default.
+  See the SVG specification for details on dashing.
+
+``--dash-offset=VALUE``
+
+  The offset into the dash pattern where dashing should begin.
+  The default value is 0.
+
+Rendering
+^^^^^^^^^
+
+The ``render`` command renders the given path as a PNG image.
+The interior of the path is filled.
+
+``--fill-rule=VALUE``
+
+  The fill rule that is used to determine what areas are inside the path.
+  The possible values are ``winding`` or ``even-odd``. The default is ``winding``.
+
+``--fg-color=COLOR``
+
+  The color that is used to fill the interior of the path or stroke the path.
+  If not specified, black is used.
+
+``--bg-color=COLOR``
+
+  The color that is used to render the background behind the path.
+  If not specified, white is used.
+
+``--output-file=FILE``
+
+  The file to save the PNG image to.
+  If not specified, "path.png" is used.
+
+``--stroke``
+
+  Stroke the path instead of filling it.
+
+``--line-width=VALUE``
+
+  The line width to use for the stroke. ``VALUE`` must be a positive number.
+  The default line width is 1.
+
+``--line-cap=VALUE``
+
+  The cap style to use at line ends. The possible values are ``butt``, ``round``
+  or ``square``. See the SVG specification for details on these styles.
+  The default cap style is ``butt``.
+
+``--line-join=VALUE``
+
+  The join style to use at line joins. The possible values are ``miter``,
+  ``miter-clip``, ``round``, ``bevel`` or ``arcs``. See the SVG specification
+  for details on these styles.
+  The default join style is ``miter``.
+
+``--miter-limit=VALUE``
+
+  The limit at which to clip miters at line joins. The default value is 4.
+
+``--dashes=VALUE``
+
+  The dash pattern to use for this stroke. A dash pattern is specified by
+  a comma-separated list of alternating non-negative numbers. Each number
+  provides the length of alternate "on" and "off" portions of the stroke.
+  If the dash pattern is empty, dashing is disabled, which is the default.

+
+``--dash-offset=VALUE``
+
+  The offset into the dash pattern where dashing should begin.
+  The default value is 0.
+
+Info
+^^^^
+
+The ``info`` command shows various information about the given path,
+such as its bounding box.
