1. Define uniforms in JavaScript to pass data to the shaders.
2. Write GLSL code for the vertex shader to manipulate vertex positions or other attributes.
3. Write GLSL code for the fragment shader to determine the color of each fragment.
4. Create a `THREE.ShaderMaterial` instance, providing the uniforms, vertex shader, and fragment shader.
5. Apply the `ShaderMaterial` to a Three.js mesh.
6. Update uniforms in the animation loop to create dynamic effects.
7. Debug and optimize the shader code for performance.
