The *Repository* pattern helps us to abstract away the way we retrieve the data. The *Repository* provides a clean API so that the rest of the app can retrieve data easily.

Before implementing the *Repository* pattern, let’s re-factor `BlogHttpClient`. Since we are not going to use the `BlogHttpClient` directly inside activity, we can remove the listener from the `loadBlogArticles` method and make it blocking call instead.

This lesson will go over the implementation of the Repository pattern.
