Hello, WordCamp Mumbai! Here’s everything you need to start using the code snippets outlined in my talk.
1) First, download the Code Snippets plugin, and install it on a test site.
2) Then, grab the code for each example from the code blocks below, or by clicking on the Gist links next to each example.
Warning: do NOT run any of this code on a live site.

add_filter( 'the_title', 'wcmumbai_add_promo', 10, 2);

return $title;
}
