+
+## Motivation
+
+- CLI's are cool
+- Spotify doesn't have an official CLI alternative
 
 ## Functionality
 
 - list the current playing song and upcoming song in queue
+- follow and unfollow artists
+- query information about playlists
 - create and delete playlists
 - add and remove songs from playlists
-- follow and unfollow other artists
+- rename playlists and update playlist description
 
 ## Technical Overview
 
+**external crates:**
 - uses the `rspotify` crate to interact with the Spotify API
 - uses the `clap` crate to help with parsing command line arguments
 
+**program structure:**
+- `src/main.rs` contains the main program
+- other files in `src/` contains the functionality for different subcommands
+
+## Challenges
+
+- all the useful Spotify API endpoints (playing songs, adding to queue, etc.)
+need a premium account
+- our Spotify for Developers program is in Development mode, which means that
+only up to 25 preselected accounts can use the application. In order to allow
+everybody to use our tool, we need to apply for an Extension Request with
+Spotify. As a result, you probably can't use this CLI tool :(
