Readme needs explanation on how to substitue assets link in template

[albertoaa]

I was reviewing the Readme and I didn't find how to use generated versioned files on my template. For instance what should I do to replace on my index.html file:
<link rel="stylesheet" href="styles/app.css">
<script src="app.js"></script>
with the appropiate asset versioned file? Something like:
<link rel="stylesheet" href="styles/app.min.f4ae3f.css">
<script src="app.271e7f.js"></script>
generated after runing the task

Register your own task and use grunt.option

grunt.registerTask('processPrepare', 'Store assets_versioning hash in variable', function () {
       grunt.option('hash', grunt.config.data.assets_versioning.dist.versionsMap[0].version);
});

Use processhtml

processhtml: {
            options: {
              process: true,
              data: {hash: '<%= grunt.option(\"hash\") %>'}
            },
            dist: {
              files: {'src/_index.html': ['src/index.html']}
            }

And in your html

<!-- /build -->
    <!-- build:template
    <script src="dist/filename.<%= hash %>.js"></script>
    /build -->
