        ## Quick Start

        1. Select desired `Pretrained Model` and adjust `Seed` to generate an
           initial image.
        2. Click on image to add control points.
        3. Click `Start` and enjoy it!

        ## Advance Usage

        1. Change `Step Size` to adjust learning rate in drag optimization.
        2. Select `w` or `w+` to change latent space to optimize:
        * Optimize on `w` space may cause greater influence to the image.
        * Optimize on `w+` space may work slower than `w`, but usually achieve
          better results.
        * Note that changing the latent space will reset the image, points and
          mask (this has the same effect as `Reset Image` button).
        3. Click `Edit Flexible Area` to create a mask and constrain the
           unmasked region to remain unchanged.
