Near the bottom of the README, I think the paragraph below should read "now persisted" instead of "not".

We added rolling_in_the_deep to adele's collection of songs and we can see the adele knows it has that song in the collection and rolling_in_the_deep knows about its artist. Not only that, rolling_in_the_deep is not persisted to the database.

The output of [16] pry(main). Output should contain the artist instance object.

It's working! But even cooler is that we've established has many through relationships. By creating a genre, then pushing a song into that genre's list of songs, the genre will now be able to produce its associated artists!

=> **#<Genre:0x007fa34338d270 id: 1, name: "pop">**
[17] pry(main)> pop.artists
=> [#<Artist:0x007fc75b8d9490 id: 1, name: "Adele">]
[28] pry(main)> adele.genres
=> [#<Genre:0x007fa34338d270 id: 1, name: "pop">]

This is snippet was copied from the second to last paragraph.

I think rolling_in_the_deep.artist in the example below should return an instance of the Artist class [#<Artist:0x007fc75b8d9490 id: 1, name: "Adele">]
