title: Compute shader and workGroup
body: <p>I want to understand how to work with compute shaders. I didn't find any details on the Internet. What is workingGroup? </p>
  
  <pre><code>layout (local_size_x = 1, local_size_y = 1, local_size_z = 1) in;
  </code></pre>
  
  <p>what it meaning?</p>
  
  <pre><code>vkCmdDispatch(cmdBuffer, 1, 1, 1);
  </code></pre>
  
  <p>Should the values in the Shader and in the function be the same?</p>
