+Intro to shaders: 2D and 3D water
+=================================
+
+.. figure:: img/intro_to_shaders_water_godot_project.png
+
+In this hands-on video series, you will create your first water shaders in 2D
+and in 3D. If you're new to shaders, you should start 2D, because you need
+some basic understanding of the shading language, vertex and fragment shaders,
+to build upon. 3D adds quite a bit of complexity when it comes to writing shader
+programs, as you will see in the third video.
+
+Watch the tutorials

+Download the source code
+------------------------
+
+Download the to the shader project here to follow along:
+:download:`2d_water_shader.zip <files/2d_water_shader.zip>`.
+
+It comes with a `start` folder to follow along with the 2D tutorials, and an `end`
+folder that contains the final code.
+
+You will find the 3D water project on `this GitHub repository
+<https://github.com/BastiaanOlij/shader_tutorial>`_. We didn't include
+it here as it is a little heavy.
