+## Description
 `fig2u3d` saves the figure as a `U3D` file for inclusion as an interactive 3-dimensional figure within a `PDF`. Either `LaTeX` or Adobe Acrobat can be used to embed the `U3D` file in the `PDF`.
 
-The `idtf2u3d` executables are needed from [this project](http://sourceforge.net/projects/u3d/). To obtain them download [this](http://www.mathworks.com/matlabcentral/fileexchange/25383-matlab-mesh-to-pdf-with-3d-interactive-object) and place the `bin` directory in the `idtf2u3d` directory of the `fig2u3d` distribution.
+The `idtf2u3d` executables are included from [this project](http://sourceforge.net/projects/u3d/) (see dependencies below).
 
 A `vws` file is also created, which contains the current camera view of the axes saved. This file can be used to set the figure's default view in the PDF to be the same with the open figure window in `MATLAB`.
 
@@ -30,17 +60,25 @@ Graphics object supported for export include:
 
 Line colors and marker styles, surfaces and `quivers` with `NaN`s and surface shading are supported. Multiple instances of various objects can be plotted in the same axes and exported. Note that some limitations apply, for example filled contours are not yet supported.

-- `fig2u3d` needs the idtf2u3d converter executable by downloading [this](http://www.mathworks.com/matlabcentral/fileexchange/25383-matlab-mesh-to-pdf-with-3d-interactive-object) and placing the `bin` directory in the `idtf2u3d` directory of the `fig2u3d` distribution.
+## Installation
 
+Download & unpack from the [release](https://github.com/johnyf/fig2u3d/releases) the:
+
+- `MATLAB` code,
+- idtf2u3d converter Mac OS X, Linux, Windows binaries, place this under `idtf2u3d/bin` (result: `idtf2u3d/bin/glx…` etc),
+- required `MATLAB` packages, place them anywhere.
+
+Add all the above and their subdirectories to your `MATLAB` path, e.g. using the `pathtool` command.
+
+### Optional
 - `fig2pdf3d` needs a latex distribution (e.g. [MikTeX](http://miktex.org/), [TeXLive](http://www.tug.org/texlive/), [MacTeX](http://tug.org/mactex/)) and [`media9`](http://www.ctan.org/pkg/media9) (preferred) or [`movie15`](http://www.ctan.org/pkg/movie15) LaTeX package (replaced by `media9`).
