nothing affecting functionality, all meta changes

- changed license to MIT
- wrote out actual README
- spotify client keys are checked for on run in config.cr
- spotify-searcher class doesn't crash now when there's a problem with the keys or authentication,
  rather it just sets @authenticated to false

+> A music scraper that understands your metadata needs.
+
+## Installation
+
+1. Download the latest release for your platform [here](https://github.com/cooperhammond/irs/releases)
+1. Create a `.yaml` config file somewhere on your system
+1. Copy the following into it
+    ```yaml
+    binary_directory: ~/.irs/bin
+    music_directory: ~/Music
+    client_key: XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
+    client_secret: XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
+    single_folder_playlist:
+        enabled: true
+        retain_playlist_order: true
+        overwrite_album: false
+    ```
+1. Set the environment variable `IRS_CONFIG_LOCATION` pointing to that file
+1. Go to [`https://developer.spotify.com/dashboard/`](https://developer.spotify.com/dashboard/)
+1. Log in or create an account
+1. Click `CREATE A CLIENT ID`
+1. Enter all necessary info, true or false, continue
+1. Find your client key and client secret
+2. Copy them into where all the X's are in your config file from above
+
+You should be good to go! Run the file from your command line to get help on usage or keep reading!
+
+##### Optionally From Source
+
+Or if you're one of those cool people who compiles from source
+
+1. Install crystal-lang ([`https://crystal-lang.org/install/`](https://crystal-lang.org/install/))
+1. Clone it (`git clone https://github.com/cooperhammond/irs`)
+1. CD it (`cd irs`)
+1. Build it (`shards build`)

+## How it works
 
-## Installation
+**At it's core** `irs` downloads individual songs. It does this by interfacing with the Spotify API, grabbing metadata, and then searching Youtube for a video containing the song's audio. It will download the video using [`youtube-dl`](https://github.com/ytdl-org/youtube-dl), extract the audio using [`ffmpeg`](https://ffmpeg.org/), and then pack the audio and metadata together into an MP3.
 
-TODO: Write installation instructions here
+From the core, it has been extended to download the index of albums and playlists through the spotify API, and then iteratively use the method above for downloading each song.
 
+It used to be in `python`, but
+1. I wasn't a fan of python's limited ability to distribute standalone binaries
+1. It was a clusterfuck of code that I made when I was little and I wanted to refine it
+2. `crystal-lang` made some promises and I was interested in seeing how well it did (verdict: if you're building high-level tools you want to run quickly and distribute, it's a joy to work in)
