 # spotify-discord-rpc
+
+## What It Does
+The name is misleading, it actually just shows anything you're currently scrobbling to LastFM on your discord rich presence. I just use it for spotify which is why I named it this. To enable LastFM scrobbling in Spotify, simply go to settings and link your account.

+
+## Dependencies
+The dependencies for building this project are two header only libraries:
+- https://github.com/nlohmann/json
+- https://github.com/yhirose/cpp-httplib
+
+
+## Config
+The `config.json` file is simple:
+```json
+{
+  "lfm_api_key": "",
+  "dsc_app_id": "388745305543147540",
+  "lfm_user": ""
+}
+```
+Place it in the same directory as the executable.
+
+`lfm_api_key` is your LastFM API key, obtained [here](https://www.last.fm/api/account/create).  
+`dsc_app_id` is the ID of the discord app to use. The one provided is one I created already, but use your own if you want to change the name or the image.  
+`lfm_user` is your LastFM username.
