+### Useful token information
+
+- Tokens contain "associated data" which is a 32-bit integer.
+- `Identifier` and `Constant` tokens will be converted into the higher-level `IdentifierToken` and `ConstantToken` classes. The associated data for these tokens resolve to entries in a table, and GDWeave can automatically convert to and from for you, as well as adding new entries to the respective tables.
+- `Newline` tokens have associated data for the given indent level.
+- `BuiltInType` and `BuiltInFunc` tokens contain the enums `VariantType` and `BuiltinFunction` respectively. You can cast these enums to a `uint?` to use them in the token constructor.

 ### Technical info
 
 - Pack files are loaded with an injected script in the first autoload. This is unstable and this behavior may change in the future.
