Enums are not documented

The only documentation for this library appears to be the README. However, this documentation is incomplete. The README documentation references several "enum-type" types, such as SyntaxKind (an enum{}) or NodeType (a union type supporting seven strings). Without knowing the allowed values of these enums, the library is not usable.

Clicking around in the github repo, I found src/main.ts, an extremely readable file with comments documenting the entire interface including the enums. I was able to use this to write my code. However a less experienced coder might not think to look for documentation in the src/ folder.

Expected behavior

All items from src/main.ts should be included in the README documentation, including the enums.

Empieza leyendo los comentarios de la interfaz en src/main.ts y comparándolos con el README actual. Documenta todos los elementos de src/main.ts, incluidos los valores permitidos para SyntaxKind y NodeType. La tarea estará terminada cuando el README cubra la interfaz completa, en lugar de obligar a los lectores a inspeccionar src/.
