 # Parser
 
-Sanitizes and standardizes InnerTube responses while maintaining the integrity of the data. Also [drastically improves](https://github.com/LuanRT/YouTube.js/blob/main/src/parser/youtube/Library.ts#L69) how API calls are made and handled. 
+Sanitizes and standardizes InnerTube responses while maintaining the integrity of the data. 
+
+Structure:
+
+* [`/classes`](https://github.com/LuanRT/YouTube.js/blob/main/src/parser/classes) - InnerTube nodes.
+* [`/types`](https://github.com/LuanRT/YouTube.js/blob/main/src/parser/types) - General response types.
+* [`/youtube`](https://github.com/LuanRT/YouTube.js/blob/main/src/parser/youtube) - Contains the logic for parsing YouTube responses.
+* [`/ytmusic`](https://github.com/LuanRT/YouTube.js/blob/main/src/parser/ytmusic) - Contains the logic for parsing YouTube Music responses.
+* [`/ytkids`](https://github.com/LuanRT/YouTube.js/blob/main/src/parser/ytkids) - Contains the logic for parsing YouTube Kids responses.
+* [`helpers.ts`](https://github.com/LuanRT/YouTube.js/blob/main/src/parser/helpers.ts) - Helper functions/classes for the parser.
+* [`parser.ts`](https://github.com/LuanRT/YouTube.js/blob/main/src/parser/parser.ts) - The core of the parser.
+* [`map.ts`](https://github.com/LuanRT/YouTube.js/blob/main/src/parser/map.ts) - A list of all InnerTube nodes, it is used to determine which node to use for a given renderer. Note that this file is auto-generated and should not be edited manually.
