Step 2: every text you want translated include the trn class
Step 2: there are multiple ways to translate your text, you can add the trn class, use the trn tag or translate attribute content with trn-attr class and a data-trn-attr attribute containing a space separated list of attributes that must be translated

<span class="trn">text to translate</span>
<span><trn>text to translate</trn></span>
<a href="/test" title="title to translate" class="trn-attr" data-trn-attr="title">Go!</a>

Instead using your text as key you can use the data-trn-key attribute to specify the key or the data-trn-key-attribute-name attribute to specify the key to use for attribute-name translation.

Step 3: create your dictionary
