Create a class and bind it to service container to initialize it

<?php
    class Fish 
    {
        public function swim()
        {
            return 'swimming';
        }

Sometimes you want to have a subdirectory on the master branch be the root directory of a repository’s gh-pages branch. This is useful for things like sites developed with Yeoman, or if you have a Jekyll site contained in the master branch alongside the rest of your code.

For the sake of this example, let’s pretend the subfolder containing your site is named dist.

Remove the dist directory from the project’s .gitignore file (it’s ignored by default by Yeoman).
